Stainless steel in the Philippines and all over the world are the most versatile of materials used in the production of different products and/or appliances. That means this kind of resource is in high demand not only for home design purposes, but as well as for industries, roadwork, and even in the medical field. While there are different companies where you can purchase stainless steel, such as One Sky Philippines, it is not enough to simply walk up to these industries without background knowledge and awareness of what you should be looking for in steel products.

In light with that, here’s a short guide on how you can trust that the stainless steel you are purchasing is of quality assurance, and will cope with any given setting or situation.

 

It is corrosion-resistant

Upon inquiring for stainless steel-made appliances or materials, the first question which you may ask the producer is whether the steel is easily damaged. You can be sure that stainless steel is quality when it passes the basic characteristic of why stainless steel is chosen as the best for different needs: it is because it has corrosion-resistant properties. You can check with the supplier on the grade of the stainless steel because corrosion resistance varies depending on its grade.

 

It is fit for welding

It Is Fit For Welding

Depending on your application for purchasing stainless steel in the Philippines, make sure that your stainless steel purchase can withstand the welding process if it needs to be welded. Take note that stainless steel is a long shot from welding carbon steel, and that corrosion may happen if you purchased the wrong stainless steel without the proper qualities to survive the welding process.

 

Its strength fits its use

Stainless steel, as mentioned earlier, comes in different grades. This means that quality assurance differs per grade and the function in which it will be integrated. Take for example a grade of 316 will be tougher and ductile than martensitic stainless steel with a grade of 440c. You may speak to knowledgeable industries like One Sky Philippines to know more about the appropriate stainless steel purchase depending on the application.

 

The company should be certified

The Company Should Be Certified

One of the simplest ways to confirm that you are getting quality stainless steel material is by looking at the certification of its producers. Other than the concern for the steel products you wish to transact, you may want to do a bit of research on your supplier and their background of legitimately providing quality-assured steel products.

 

Observe its formability

You want to own stainless steel which does not possess weak formability; the kind of steel which turns brittle when used excessively and performs poorly will not pass for quality assurance. Again, this comes down on the topic of grades. Whether you want slabs, bars, or sheets will be delivered a wide range of forms. For example, martensitic steels are often sold in bars or slabs.

 

Check if it needs heat treatment

Check If It Needs Heat Treatment

Different stainless steel grades respond in contrasting ways when it comes to heating and hardening. Just like welding, review on what kind of stainless steel quality will be offered upon stating its application. There are stainless which are not very heat resistant and might deform on the slightest change in temperature.

 

Quality assurance means guidance

It is also the stainless steel manufacturer’s job to guide consumers on the proper steel which is fit for their needs. Even when purchasing stainless steel appliances in malls, the seller must be able to point out distinct characteristics which the steel product will have its positive and negative points.

 

Look for a model

Look for a model

In order to further test the quality assurance of stainless steel, you might want to request a ready-made product/output which incorporates the material in order to better observe the aspect of how the stainless steel works. You may even request a demo of the product just to prove its trait. This may fall into quality assurance testing.

 

Feedback is readily accepted

There are times when expected quality does not live up to what is promised or promoted. Still, you can vouch for the company’s credibility of providing better service and quality when they are ready to welcome mistakes and/or feedbacks thrown at them, and they make it a point to improve their product’s quality and marketing.

 

Key Takeaway

Quality assurance in stainless steel must be sought for as stainless steel is one of the prominent materials used in different fields—from architecture to medicine. You need a promising material when purchasing stainless steel. Always keep these in mind when you find yourself in the process of acquiring stainless steel. Do not aim for just the product, but aim for a service you can trust, and you respect.

Stainless Steel in the Food Industry

Stainless Steel In The Food Industry

Why stainless steel is popular for the food industry?

  1. Corrosion resistance
  2. Easy fabrication
  3. Easy to clean
  4. Heat resistance
  5. Maintains freshness

 

With the various applications that we often associate this resource with everyday materials and household products, stainless steel in the Philippines is the most widely used metal in the country. But did you know that stainless steel is commonly used in the food industry? Stainless steel has played a huge role in transporting and producing food in factories and other food-related institution. Let’s find out why this amazing metal is so popular:

 

Corrosion Resistance

When it comes to metals and the food industry, stainless steel is the best choice for packaging food or beverages in metal containers. Stainless steel in the food industry can be found in various processes; from food manufacturing to packaging. In the Philippines, stainless steel products are often used when handling food, like knives, pots, forks, and spoons.

The reason for this is because stainless steel has a natural ability to resist the effects of corrosion. Due to the presence of chromium in stainless steel, the effects of oxidation don’t cultivate or promote the steel to rust. Instead, it passively forms a barrier on the surface of the stainless steel that enhances its resilience against corrosion. You don’t have to worry about corroded steel making contact with food when stainless steel is used.

 

Easy Fabrication

Easy Fabrication

A major benefit of stainless steel is its ease of fabrication. Steel designers can enjoy the extensive boundaries of design when crafting something made of stainless steel. Its ease of fabrication plus many other qualities is another reason for stainless steel to be the top choice for the food industry. With stainless steel, it’s possible to achieve a perfectly smooth fabricated surface that is free of cracks, crevices, and a jagged exterior. This prevents the buildup of bacteria and the cultivation of harmful microorganisms.

You may notice that the design of stainless steel containers, vats, and tubing in the food industry are often made with no sharp joints, few angles, and less channeling parts. Expert craftsmen are involved with the fabrication of these as the welds need to be expertly crafted with no broken areas. Sharp angles and hard corners are strictly avoided due to those designs being susceptible to cracking under stress and other structural issues.

 

Easy to Clean

Knowing that most stainless steel materials in the food industry are designed with smooth surfaces and no angled areas, that means that stainless steel in the food industry is easy to clean. As a result, stainless steel can dramatically prevent any harmful bacteria from sticking on the surface of the metal. It isn’t difficult to decontaminate and sterilize stainless steel; which is why, alongside many other reasons, it’s the best choice of metal that is used in the food industry.

Apart from the food industry, you can easily find stainless steel countertops and food-related appliances. Why are these good choices? Because it’s non-porous and cleanup is a breeze. You don’t have to vigorously wipe the surface of stainless steel to keep it clean. Simple strokes with a rug and milk soap will do the trick.

 

Heat Resistance

Heat Resistance

In the food industry, temperature changes are a constant variable in the process of producing any form of food consumables. This is prominent in the beverage industry. The shift from cool to extreme heat and back to room temperature happens every minute. There is no better material to handle these sporadic temperature changes than stainless steel.

For many other metals, elevated temperatures will rapidly deteriorate the quality of the metal, making it prone to the effects of oxidation. At temperatures reaching 2000 degrees Fahrenheit, stainless steel can still effectively resist corrosion. You’ll notice that a production line in the food industry where products are heated involve the use of stainless steel contraptions and machinery. Another great property of stainless steel under the effects of elevated temperatures is its ability to maintain its shape and structural rigidity. Not easily cracking, warping, breaking, or buckling.

 

Maintains Freshness

Because stainless steel containers don’t leach any contaminants, it’ll preserve a food’s freshness for days, weeks, or even months. Naturally, stainless steel provides chemical and bacterial neutrality. How else does stainless steel maintain the freshness of the food or beverage stored? When it comes to cooked food and goods that contain additives, naturally, these foods or goods will produce some amount of alkalis and acids, which could slowly deteriorate the quality of some metals. Stainless steel is naturally inert to the deteriorating effects of acids and alkalis.

 

Key Takeaway

The use of stainless steel in the food industry has helped us preserve and transport food with minimal to no complications. We can see these in syrup tanks, wine containers, knives, spatulas, and evaporator tubes. Though a simple and common metal material, its benefits make it one of the best resources that helped shape the way the food industry works and ultimately, the way we live.

Stainless Steel Philippines: Types of Corrosion

Stainless Steel Philippines Types Of Corrosion

What are the different types of corrosion?

  1. General Attack Corrosion
  2. Galvanic Corrosion
  3. Localized Corrosion
  4. Environmental Cracking
  5. High-Temperature Corrosion

 

Metal and stainless steel in the Philippines are widely used as a primary material for many industries. They’re tough, readily available, and can be used for various applications. Though metals aren’t indestructible, they have one major weakness. Corrosion may be caused by many different conditions and factors, let’s take a look at a few different types of corrosion:

 

General Attack Corrosion

This is the most common type of corrosion; it is also commonly known as uniform corrosion. It is considered to be an even attack of oxidation across the surface of a metal material. This form of corrosion is usually easy to determine because it is relatively simple to replicate and reproduce its effects with consistency. Usually, causes of this form of corrosion are due to chemical exposition or from an electrochemical reaction.

From this point, general attack corrosion will render the full deterioration of the metal to the point of structural failure. As mentioned earlier, it’s the most common type of corrosion, which correlates to this type of corrosion accounting for the greatest amount of metal destruction via corrosion. Since it’s common, it isn’t difficult to prevent and predict. Oftentimes, a metal that succumbs to this type of corrosion is still manageable and even preventable.

 

Galvanic Corrosion

Galvanic Corrosion

Galvanic corrosion, often times called dissimilar metal corrosion happens when two dissimilar metals are in contact with one another and in the presence of an electrolyte. This usually happens at metal structural locations such as joints or weld spots. To know how this type of corrosion occurs involves taking a deeper look at metals from a molecular level.

Three conditions must be met in order for this type of corrosion to occur. First, the metals in contact must be electrochemically different. Second, the metals in contact must be electrically connected. Third, the metals must be exposed to an electrolyte. When these conditions are met, one metal starts giving its electrons to the other metal or it becomes an anode, while the other receives the electrons or becomes a cathode.

In Galvanic corrosion, the anode will begin to rapidly rust with the cathode will become more resistant to corrosion. A common example of this is when copper and steel are linked together and suddenly become exposed to salt water.

 

Localized Corrosion

Under localized corrosion, we have three types: pitting, crevice, and filiform corrosion. These types of corrosion target a specific area in a metal’s structure.

  • Pitting Corrosion – is one of the most difficult types of corrosion to spot. It happens when a cavity is formed in the metal. What happens in the cavity is that the exposed area experiences a loss in electrons, the anodic area then becomes more susceptible to a localized form of galvanic corrosion. This cavity will weaken the structure of the metal from within, leading to potential failure.

 

  • Crevice Corrosion – crevice corrosion is similar to pitting corrosion but it doesn’t involve any electron loss. This type of corrosion happens when a cavity, small hole, or crevice in a metal becomes exposed to a stagnant microenvironment. Because of the acidic environment or the exhaustion of oxygen in a crevice, this will lead to corrosion.

 

  • Filiform Corrosion – One of the subtlest corrosions that can slip under the guise of many, filiform corrosion is a form of corrosion that happens under any form of coating. Common instances that because filiform corrosion is when a coating breach occurs and water slips in between the metal and its coating. This form of corrosion spreads underneath paint, epoxy, and many other forms of coating to cause structural weakness.

 

Environmental Cracking

Environmental Cracking

Environmental cracking is a common form of corrosion that occurs to metals exposed to various environmental conditions. Oxidation, temperature change, and chemical exposure are a few factors that contribute to various structural damages such as stress corrosion cracking, metal embrittlement, corrosion fatigue, and hydrogen induced cracking.

 

High-Temperature Corrosion

Often caused by high-temperature oxidation and carbonization, high-temperature corrosion typically happens in vehicle’s turbochargers, diesel engines, and exhaust pipes. This happens due to the fuels used in these types of machines; during combustion, various compounds attach themselves to the metal and quickly corrode the surface. At times, even stainless steel may rust due to high-temperature corrosion.

In the Philippines, stainless steel products that are exposed to high-temperature corrosion usually don’t mean that structural integrity will be compromised. Typically, in older engines, you may notice that the exhaust side of a turbocharger will always be more rusted compared to the intake side, but it still works well.

 

Key Takeaway

Knowing the different types of corrosion can help you determine whether your metal structure, parts, or components can be saved and how they can be remedied. With this knowledge, you can somehow pinpoint the causes of corrosion and prevent them from happening.
