Custom 455® Stainless Steel Bar - ASTM F 899
Custom 455® is a martensitic, age-hardenable stainless steel. This alloy represents a significant advancement in precipitation hardening stainless steel. Custom 455® has three times the yield strength of standard 304. It lends itself well to heat treatment and fabrication and has exceptionally high yield strength, good ductility, and toughness. Custom 455® resists staining in normal atmospheres and shows no corrosion in freshwater.
