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.

Hot Working Any hot work should commence at 2100-2150 F and finish at 1800 F.

Cold Working Due to its relatively high strength and work hardening rate, 330 is more difficult to cold form than standard 18-8 stainless steels. Expect to use higher forces than normal and note its’ elevated springback.

Annealing Soak at 2050-2200 F, air quench.

Hardening 330 will not respond to heat treatment.; it will only harden upon cold reduction.
