Material Notes:

Crucible 174 SXR is a premium quality precipitation- hardening stainless steel designed for use as rifle barrels. It is a modification of Crucible’s 17Cr-4Ni which offers substantially improved machinability without sacrificing toughness. Its excellent corrosion resistance approaches that of a 300 series austenitic stainless steel, while its high strength is characteristic of 400 series martensitic stainless steels. At similar hardness levels, Crucible 174 SXR offers greater toughness than either the 410 or the 416 stainless steels which are commonly used for rifle barrels.Information provided by Crucible Industries
