Alloy 330 is an austenitic heat and corrosion resisting alloy that offers a combination of strength and resistance to carburization, oxidation and thermal shock. This alloy was designed for applications in high temperature industrial environments where good resistance to the combined effects of carburization and thermal cycling are required, such as the heat treat industry. Carburization and oxidation resistance to about 2100°F are enhanced by the silicon content of the alloy 330 stainless remains fully austenitic at all temperatures and is not subject to embrittlement from sigma formation. It has a solid solution composition and is not hardenable by heat treatment. The alloy's strength and oxidation resistance at high temperatures make it a useful material for industrial heating furnaces.
Alloy 330 Nickel base steel usually used in the following industries :
Furnace containers-carburizing, carbonitriding, annealing malleablizing
Muffles, retorts
Bar frame heat treating baskets
Quenching fixtures
Radiant tubes
Salt pots
Furnace fans and shafts
Conveyors
Tube hangers for crude oil heaters adn steam boilers
Heat exchangers

Corrosion Resistance
330 steel offers a high level of corrosion resistance, particularly to oxidation, carburization and nitridation. In aqueous environments, the alloy's chromium content provides resistance to oxidizing conditions while its nickel content imparts resistance to reducing conditions. The high nickel also gives 330 good resistance to chloride-ion stress- corrosion cracking.
Fabrication with Alloy 330
Alloy 330 is readily fabricated by standard commercial procedures. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly. Alloy 330's rate of work hardening is comparable to austenitic stainless steels.
Alloy 330 Nickel base steel characteristics:
Oxidation resistance to 2100°F
Resistant to carburization and nitriding
Resistant to thermal shock
Good strength at elevated temperature
Chloride ion stress corrosion cracking resistance
