What is 317L stainless steel?

317L (00Cr19Ni13Mo3, UNS S31726) alloy is an austenitic stainless steel based on molybdenum.

Compared with conventional chromium-nickel austenitic stainless steels such as 304 alloy, it has stronger resistance to chemical corrosion. In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. It is a low carbon grade or L grade. This grade has anti-sensitizing properties during welding and heat treatment.

Manufacturing Process for 317L Stainless steel

Conventional hot working processes can be performed. The material should be heated to 1149-1260°C (2100-2300°F); however, it should not be heated below 927°C (1700°F). To optimize corrosion resistance, a post-work annealing is recommended.

Shearing, stamping, heading and drawing are possible with grade 317L stainless steel, and post-work annealing is recommended to eliminate internal stresses. Annealing is performed at 1010-1121°C (1850-2050°F), which should be followed by rapid cooling.

Grade 317L stainless steel does not respond to heat treatment.
