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

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

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.

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

Hot Working 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.

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

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.
