What is 309 Stainlesss Steel?

Stainless steels are called as high-alloy steels. Due to the presence of large amounts of chromium in the range of 4 to 30%, they have high corrosion resistance than other steels. Stainless steels are classified into martensitic, ferritic and austenitic based on their crystalline structure. However, stainless steels present in the form of a combination of martensitic and austenitic steels are known as precipitation-hardened steels.
