13-8Mo

13-8 Mo VIM-VAR steel is a precipitation hardening martensitic stainless steel offering excellent fracture toughness and transverse mechanical properties coupled with the resistance to stress-corrosion cracking and high strength characteristics common to the family of precipitation hardening steels. A wide range of mechanical properties can be realized by selecting various single cycle low temperature aging treatments. The alloy is double vacuum remelted (vacuum induction melted followed by vacuum arc remelting) to consistently assure low gas content, improved homogeneity and superior cleanliness. This alloy should be considered for applications requiring a combination of stress-corrosion resistance and high strength properties.
