17-4 Annealed (Type 630)

  • 17-4 Annealed (Type 630)

     

    17-4 stainless steel ( Grade 630 )  is an age-hardening martensitic alloy combining high strength with the corrosion resistance of stainless steel. Hardening is achieved by a short-time, simple low-temperature treatment. Unlike conventional martensitic stainless steels, such as type 410, 17-4 stainless steel is quite weldable. The strength, corrosion resistance and simplified fabrication can make 17-4 stainless steel a cost-effective replacement for high strength carbon steels as well as other stainless grades.
