Stainless steels are high-alloy steels with good corrosion resistance because of large amounts of chromium present in them. About 10% of chromium is present in most stainless steels.
Stainless steels are available in three different groups based on their crystalline structure. These groups include martensitic, austenitic and ferritic. The combination of martensitic and ferritic steels forms a fourth group of stainless steels known as precipitation-hardened steels.
Grade 440B stainless steel is a high bon martensitic stainless steel containing good strength, moderate corrosion resistance and ability to obtain and maintain wear resistance and excellent resistance.
