Custom 450
A martinsitic precipitation hardening steel, Custom 450 mstainless steel offers high strength combined with excellent corrosion resistance similar to 304 stainless in corrosion resistance with moderate strength similar to that of 410 stainless. As with most precipitation hardened alloys, Custom 450 stainless has excellent transverse properties.
Used when ease of welding and brazing in fabrication is required. Custom 450, unlike many precipitation hardening grades, Custom 450 can be used in the annealed condition.Applications
Valve parts, Paper mills, aircraft and power generation, chemical processing, nuclear and space craft.
