Armco 201 stainless steel is a non-hardenable austenitic chromium-nickel-manganese stainless steel that is capable of easily attaining high tensile strengths while maintaining excellent ductility when moderately or severely 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 forming, heat treating, and joining. Filing Code: SS-809. Producer or source: AK Steel Inc.

Types 309 and 309S are austenitic chromium-nickel stainless steels that provide excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures. Type 309S is identical to Type 309 except for a lower carbon content that minimizes carbide precipitation and improves weldability. Typical uses include furnace parts, heating elements, aircraft and jet engine parts, heat exchangers, carburizing-annealing boxes, sulfite liquor handling equipment, kiln liners, boiler baffles, refinery and chemical processing equipment, and auto exhaust parts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-853. Producer or source: AK Steel Inc.

Armco 321 is an austenitic nickel-stainless-steel with the carbon stabilized by titanium for welding and elevated temperature service. It is useful when the weldment is not annealed after welding. This alloy is nonmagnetic when annealed but is slightly magnetic when cold worked. It has excellent resistance to corrosion and oxidation, possesses high creep strength, and may be used at temperatures up to 871 C (1600 F). Titanium is added to this alloy to impart substantial immunity to intergranular corrosion. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-810. Producer or source: AK Steel Inc.

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.

Carlson alloy Nitronic 30 is a nitrogen-strengthened austenitic stainless steel providing aqueous corrosion resistance combined with resistance to abrasives and metal-to-metal wear. It has higher mechanical properties than standard austenitic grades and outstanding corrosive wear resistance under many different sliding conditions. Its galling resistance is equivalent to that of AISI Type 304. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-814. Producer or source: G.O. Carlson Inc.

Carlson alloy Nitronic 33 has twice the yield strength of 304 stainless with comparable corrosion resistance. The low magnetic permeability of the alloy is retained after severe cold working. The resistance to chloride stress-corrosion cracking is superior to Type 304. Nitronic 33 has excellent strength and ductility at cryogenic temperature, and wear and galling resistance is superior to the standard austenitic grades. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on low temperature performance and corrosion resistance as well as forming and joining. Filing Code: SS-931. Producer or source: G.O. Carlson Inc., Electralloy.
