Stainless steels are known as high-alloy steels. They consist about 4-30% of chromium. They are classified into martensitic, austenitic, and ferritic steels based on their crystalline structure. Grade 317 stainless steel is a modified version of 316 stainless steel. It has high strength and corrosion resistance.
