The alloy XM-12 / S15500 combines good strength, transverse toughness and ductility, hardness capability and corrosion resistance compared with 304 stainless. It may be used in the solution treated condition or heat treated to obtain a wide variety of properties.
15Cr-5Ni is a martensitic precipitation hardening stainless steel offering high strength and hardness along with excellent corrosion resistance. Generally similar to Custom 630 (17Cr-4Ni) in composition and properties, 15Cr-5Ni is chemically balanced to eliminate all but trace amounts of delta ferrite, thus providing superior transverse toughness and ductility plus a higher degree of forgeability.
