Chemistry Data : 

Principal Design Features		The strength of this alloy is a combination of good strength and corrosion resistance in temperatures up to 2100 F (1149 C). Due to its relatively high chromium and nickel content it is superior in most environments to 304 or 309 stainless.

Applications		Oven linings, boiler baffles, fire box sheets, furnace components and other high temperature containers.

Machinability		This alloy machines similarly to type 304 stainless. Its chips are stringy and it will work harden rapidly. It is necessary to keep the tool cutting at all times and use chip breakers.

Welding		Most of the austenitic stainless steels can be readily welded using fusion or resistance methods. Oxyacetylene welding is not recommended. Filler metal should be AWS E/ER 310.

Hot Working		Most common hot work methods can be successfully performed after uniform heating to 2150 F (1177 C). Do not forge below 1800 F (982 C). Rapid cooling is required to maximize corrosion resistance.

Cold Working		Although this alloy has a high work hardening rate, it can be drawn, headed, upset, and stamped. Full annealing is required after cold work to remove internal stress.

Annealing		1900-2050 F (1038-1121 C) water quench.

Hardening		This alloy does not respond to heat treatment. Cold work will cause an increase in both hardness and strength.
