AISI Type 305 is an austenitic chromium nickel stainless steel with lower rate of work hardening than Type 302 or 304 and less change of magnetic permeability when cold worked. 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 heat treating, machining, and joining. Filing Code: SS-154. Producer or source: Alloy steel mills and foundries.
