Principal Design Features		305 has the lowest work and strain hardening rate of all the austenitic stainless steels. It was designed for maximum formability. It combines good strength and corrosion resistance and is readily available in strip and some bar sizes from the mills.

Applications		Any application requiring maximum formability such as spun or deep drawn eyelets, barrels, shells, cold headed rivets or screws will work well.

Machinability		Slow speeds and heavy feeds are recommended to combat the material's tendency to glaze during machining.

Welding		Most of the common fusion and resistance methods can be used here. Filler metal, if necessary, should be AWS E/ER308. Oxyacetylene welding is not recommended.

Hot Working		Forging, heading and other hot working should follow uniform heating to 2100-2300 F (1149-1260 C). Rapid cooling is necessary to attain maximum corrosion resistance in finished parts.

Cold Working		Cold work is one of the design strengths of this alloy. It can be drawn, spun, headed and blanked readily due primarily to its low work hardening rate.

Annealing		1850-2050 F (1010-1121 C) followed by rapid cooling.

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