AQUAMET 18 is a low-nickel austenitic stainless steel having seawater corrosion resistance better than AISI Type 304 and approaching that of AISI Type 316 stainless steel. Its good strength and super toughness make it an ideal material for pleasure and work boats. This datasheet provides information on composition, physical properties, 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-332. Producer or source: Armco Steel Corporation, Advanced Materials Division.
