Jan 27, 2019· Stainless Steels . Stainless steels generally contain between 10-20% chromium as the main alloying element and are valued for high corrosion resistance. With over 11% chromium, steel is about 200 times more resistant to corrosion than mild steel. These steels can be divided into three groups based on their crystalline structure:
STAINLESS STEELS •Stainless steels -A group of steels that contain at least 11% Cr. Exhibits extraordinary corrosion resistance due to formation of a very thin layer of Cr203 on the surface. UCategories of stainless steels: •Ferritic Stainless Steels - Composed of a ferrite (BCC) •Martensitic Stainless Steels a-. Can be heat treated.
Stainless steels are commonly grouped into martensitic stainless steels, ferritic stainless steels, austenitic stainless steels, duplex (ferritic-austenitic) stainless steels, and precipitation-hardening stainless steels. Alloying metallic elements added during the making of the steel increase corrosion resistance, hardness, or strength.
