Sandvik 430 (Plate and sheet)
Datasheet updated 2012-08-03 09:36:07 (supersedes all previous editions)
Sandvik 430 is a ferritic stainless steel with minimum 16% chromium. Due to its ferritic structure Sandvik 430 has a lower tensile strength, elongation and impact resistance than the austentic stainless steels. The proof strength is somewhat higher.
