ATI 20-25+Nb is an austenitic stainless steel intended primarily for elevated-temperature service. This alloy fills a performance gap between conventional heat-resistant stainless steels and nickel-base superalloys, providing high performance with an economical composition. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: SS-1331. Producer or source: ATI.

Allvac 718-OP is a versatile alloy that is vacuum induction melted followed by a consumable melting process. The alloy is a special chemistry vacuum melted version of standard Allvac 718. It is a precipitation-hardenable, nickel-base alloy that can be used from -253 deg C (-423 deg F) to 704 deg C (1300 deg F). The main hardening constituent is a niobium-containing gamma prime precipitate. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on low and high temperature performance, and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-605.
