What is stainless steel?
Stainless steel (stainless steel) or the so-called stainless steel has a lot of chromium in its composition. The minimum chromium used in stainless steel is about 11%. This chromium gives the plain steel its corrosion resistance. By adding other elements such as molybdenum, nickel and nitrogen, this metal increases its resistance to corrosion and heat resistance. In order for this type of steel to react against rust and work well, the amount of chromium used in it should not be less than this amount. Because the presence of this amount of chromium in steel creates anti-rust properties. In simpler terms, chromium is an element that strengthens steel’s resistance to rust.
In addition to chrome, other compounds are also used to produce stainless steel. Molybdenum and nickel can be mentioned among these compounds. Nickel is used to create flexibility and increase formability in stainless steel. The discovery of stainless steel was that scientists found that by adding about 10-20% of chromium and nickel to existing steel, another type of steel is obtained that is resistant to acids and rust. In our daily life, we come across things that are made of steel; Such as electrical appliances, fishing equipment and many others.
This type of steel is shiny and easily polished. For this purpose, stainless steel is used as a substitute for spotlights and mirrors.
Stainless steel is a type of steel product that has a large amount of chromium in its composition and is produced to increase corrosion resistance. This product is available in different types, each of which has wide applications in different industries.
All types of stainless steel
Stainless steels are usually classified into five different classes based on their chemical and metallurgical composition:
- Martensitic
- Ferritic
- Austenitic
- Austenitic-ferritic or two-phase (Duplex or ferritic-austenitic)
- Precipitation-Hardening or PH
