Attributes:

 

430 Stainless steel grade is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels. known for its good corrosion resistance and formability, coupled with practical mechanical properties. It can be used in certain chemical applications due to its resistance to nitric acid.

At the solution treating temperature, 1900°F, the metal is austenitic but undergoes transformation to a low-carbon martensitic structure during cooling to room temperature. This transformation is not complete until the temperature drops to 90°F. Subsequent heating to temperatures of 900-1150°F for one to four hours precipitation strengthens the alloy. This hardening treatment also tempers the martensitic structure, increasing ductility and toughness. 

APPLICATIONS:

  • Fasteners

  • Gears

  • Stems

  • Shafts

  •  Pins
