Carlson 330 Austenitic Alloy
Categories:	Metal; Nonferrous Metal; Nickel Alloy
Material Notes:	General Description Carlson Alloy 330 is a nickel-iron-chromium-silicon austenitic alloy. It combines high strength with excellent resistance to carburization and oxidation at temperatures to 2200°F (1200°C). 330 remains completely austenitic at all temperatures; and is totally immune to sigma phase formations. With a 34 to 37 percent nickel content, 330 is highly resistant to chloride stress corrosion cracking. This high temperature alloy is often utilized for applications where conventional austenitic stainless steels are marginal. Applications 330 is used extensively in elevated temperature environments where resistance to the combined effects of thermal cycling and carburization is required. Furnace Containers – annealing, carbonitriding, malleablizing. Heat Treating Equipment – muffles, retorts, conveyor systems, baskets, boxes, quenching fixtures. Gas Turbine Components Heat Exchangers Furnace Fans Petrochemical Furnace Parts Salt Pots – neutral, cyanide Hot Pressing Platens. Information provided by Carlson
