330 Stainless Steel is a heat and corrosion-resistant alloy designed for high-temperature applications. With a unique composition of iron, nickel (34-37%), and chromium (17-20%), this alloy offers exceptional oxidation resistance up to 2100°F (1149°C). Its superior strength and carburization resistance make it ideal for demanding environments such as heat treatment equipment, industrial furnaces, and petrochemical applications. Unlike standard stainless steels, 330 maintains its structural integrity under extreme thermal cycling, preventing scaling and deformation. It also exhibits excellent resistance to stress corrosion cracking in high-temperature settings (Check out our 316 vs 330 stainless comparison.

330 stainless steel is a high-temperature, oxidation-resistant austenitic stainless steel known for its excellent resistance to heat, carburization, and thermal shock. It’s primary elements are Nickel, Chromium, & Iron. Some trademarked alloys can contain up to 1% of copper. This adds to its corrosive resistance. It is commonly used in extreme temperature applications, such as industrial furnaces, heat exchangers, and petrochemical processing.
330 Stainless Steel has a higher nickel content than 316 or other stainless steels. This gives it superior high-temperature strength.
