Stainless Steel is a group of heat and corrosion resisting steels. They have in general a higher resistance to corrosion in some definite environment, as well as a higher resistance to scaling at high temperature.
Stainless Steel are iron-based alloys containing a minimum of 10.5% Chromium with or without other alloying elements. Based on the alloy content and the micro structure, stainless steels are classified into three major categories viz. Austenitic, Ferritic and Martensitic.
This category of stainless steel contains 16 to 26% Chromium and 6 to 22% Nickel. they are nonmagnetic annealed condition and have excellent corrosion resistance. They are not hardenable by heat treatment. However, they can develop high strength on cold working. They have excellent weldability, formability, hygiene factor and cryogenic properties. On cold working they exhibit different degrees of magnetism. They are identified in the AISI 300 series.
This category of stainless steel contains 10.5 to 30% chromium without any Nickel. They are Ferro magnetic in nature and generally not hardenable by heat treatment. These steels possess good resistance to stress corrosion cracking and moderate weldability & formability. They are identified in the AISI 400 series.
This group contains 11 to 14% chromium without any nicket, but with a higher carbon content compared to the Austenitic and ferritic stainless steels. They are ferro-magnetic in nature and are hardenable by heat treatment. They possess moderate corrosion resistance
and are identified in the AISI 400 series.
