330 Stainless Steel

Products Offered:

We also stock safety grating, hex metal, FRP grating, and custom fabrication of all of our products.

Principal Design Features: 330 is an austenitic, nickel-chromium-iron-silicon alloy. It combines excellent resistance to carburization and oxidation at temperatures up to 2200 F(1200 C) with high strength.

Applications: Extensively used in high temperature environments where resistance to the combine effects of thermal cycling and carburization is necessary. Used in a variety of furnace components as well as in gas turbines, heat exchangers, general heat treating equipment and neutral and cyanide salt pots.

Machinability: With proper practices this alloy can be satisfactorily machined. Slow speeds, positive feeds, sulphurized lubricants and rigid mounts are generally recommended.

Welding: Can be successfully welded using GAW techniques. Use either 330 or Inco 800 filler materials.
