CarTech 15Cr-5Ni is a martensitic precipitation hardening stainless steel offering high strength and hardness along with excellent corrosion resistance. Generally similar to CarTech Custom 630 (17Cr-4Ni) in composition and properties, CarTech 15Cr-5Ni is chemically balanced to eliminate all but trace amounts of delta ferrite, thus providing superior transverse toughness and ductility plus a high degree of forgeability.

CarTech 15Cr-5Ni has fabrication characteristics similar to those of other precipitation hardening stainlesses, and can be aged-hardened by a single step, low temperature treatment.

It has been used for applications requiring high transverse strength and toughness, such as valve parts, fittings and fasteners, shafts, gears, engine parts, chemical process equipment, paper mill equipment, aircraft components and nuclear reactor components.
