Stainless steel is a steel alloy with a minimum of 10.5 percent chromium content by mass. The chromium in stainless steel has a great affinity for oxygen, and forms a film of chromium oxide on the surface of steel at molecular level. The film itself is thin, and is described as tenacious, passive and self-renewing. It resists oxidation and makes the alloy corrosion resistance. Elements such as molybdenum and nickel are also added to steel to improve corrosion resistance. There are many families of stainless steels at Toma Metals Inc designed for different uses and applications. The initial and most important step towards the successful use a stainless steel coil is selection of the proper type for the application. Here are top three aspects to consider when choosing StainlessSteel Coils.
Resistance to Corrosion
Corrosion resistance is one of the key features of stainless steel, but also the most difficult to assess for a given application. General corrosion to chemicals and natural condition is comparatively easy to determine. However, localized forms of corrosion such as crevice corrosion in tight spaces, inter-granular attacks, pitting attacks and stress corrosion cracking can be difficult to identify. Such localized corrosion can result in unexpected catastrophic failure while most of a structure is unaffected. Thus, it must be considered during steel selection.
Mechanical Properties
Aside from considering the mechanical properties of steel at service temperature, it is important to ensure satisfactory properties at other temperatures likely to be experienced. Considering these performance requirements can help to ensure the longevity of steel.
Fabrication and Cleaning Requirements
Before choosing a stainless steel coil, consider its fabrication characteristics, such as weldability and formability. Some grades of stainless have good fabrication characteristics making them cheaper to fabricate. Apart from fabrication, it is essential to consider the cleaning procedures used. Note that cleaning mediums, such as nitric-hydrofluoric acid can attack sensitized stainless coils.
These are some of the top factors to consider when choosing Stainless Steel Coils. Remember to choose a certified stainless steel supplier, to get quality stainless steel plates, coils and sheets at a reasonable price.
