Carpenter Technology Corporation’s Custom 465® stainless steel is a state-of-the-art alloy which has seen its applications expanding at a rapid rate. This alloy is a premium double vacuum melted (VIM/VAR) martensitic precipitation hardening stainless steel that offers an excellent combination of strength, toughness, and corrosion resistance. With its exceptional properties, design engineers have specified the alloy for high-performance components in various industries, such as aerospace, industrial, energy, consumer and medical. The high strength, greater than 250 ksi (1722 MPa) typical, and toughness of the alloy have allowed Custom 465 stainless to be used as a high-strength upgrade to conventional PH stainless steels such as 13-8 and 17-4. The addition of corrosion resistance to the high strength and toughness properties has allowed the alloy to be used as a stainless alternative to non-stainless steels such as AISI 4340 and 300M. This paper will compare mechanical and corrosion resistance properties of Custom 465 stainless steel to those of other PH stainless steels such as 17-4, 15-5, and 13-8, as well as to those of other aerospace alloys such as 300M and AerMet® 100 alloy. In addition, examples of the varied uses of the alloy will be provided, these examples will highlight the benefits obtained by the use of Custom 465 stainless steel over the previous alloys of choice for the applications.

Abstract 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 that 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 416 stainless steels which are commonly used for rifle barrels. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming and heat treating. Filing Code: SS-1034. Producer or source: Crucible Service Centers.
