Stainless Steel Material

Description | Specs

Stainless Steel is corrosion resistant because it contains chromium which, when exposed to oxygen, creates an invisible protective film, unlike carbon steel.

 It is classified into three groups ( based on their ability to be hardened) 

1. Austenitic
   1. Can be hardened by cold working, which meets a wide rainge of design criteria
   2. Non- magnetic

                           i.      Become slightly magnetic due to cold working

1. Martensitic stainless steel
   1. Straight-chromium types
   2. Hardened by heat treatment
   3. Magnetic
2. Ferritic Stainless Steel
3. 1. Like Martensitic
   2. Straight-chromium types
   3. Magnetic
   4. Cannot be hardened by heat treating and only moderately hardened by cold working
