Stainless 317

Annealing Procedure

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

Applications

Textile, pulp paper and chemical equipment, for corrosion resistance.

Cold Workability

Shearing, stamping, heading and drawing can be successfully performed . To remove internal stresses, a post-work annealing is recommended.

Hardening Procedure

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

Hot Workability

All common hot working processes are possible with this alloy. Heat to 2100-2300 F (1149-1260 C). Avoid working this material below 1700 F (927 C). For optimum corrosion resistance, a post-work annealing is recommended.

Machinability

Low speeds and constant feeds will minimize this alloy's tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended.

Principle Design Features

317 is a higher chromium, nickel and molybdenum version of 316 stainless designed principally for increased strength and corrosion resistance.

Weldability

All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER317 or 317L filler metal for best results.
