AQUAMET 22 is an austenitic stainless steel with an outstanding combination of strength, toughness and corrosion resistance. Its corrosion resistance is equal to or better than any other boat shafting material, even better than most high-nickel alloys. It is the best material available for pleasure both shafts, considering that pleasure boats spend much of their time tied up at docks where corrosion factors may be highest. 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-338. Producer or source: Armco Steel Corporation, Advanced Materials Division.
