Abstract

ALLEGHENY LUDLUM AL 2205 ALLOY is in the family of duplex alloys in which added nitrogen significantly improves corrosion resistance, especially in the welded condition. The microstructure consists of a balanced mixture of austenitic and ferritic phases. Its corrosion resistance to many environments is superior to Types 316 or 317 and it has a yield strength more than double that of AISI conventional austenitic stainless steels. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, and machining. Filing Code: SS-462. Producer or source: Allegheny Ludlum Corporation.
