(UNS S31700/S31703) 317/317L Stainless Steel Bars
317 stainless steel, also known as UNS S31700 and Grade 317, is primarily comprised of 18% to 20% chromium and 11% to 15% nickel along with trace amounts of carbon, phosphorus, sulfur, silicon and balanced with iron.
UNS S31700/S31703 commonly known as 317/317L Stainless Steel is the low carbon content version of Stainless Steel 317 for welded structures.
Features and advantages of both 317 Stainless Steel and 317L Stainless Steel include increased strength, corrosion resistance (including crevice and pitting), higher tensile strength and a higher stress-to-rupture ratio. Both grades resist pitting in acetic and phosphoric acids. With respect to cold working of 317 Stainless Steel and 317L Stainless Steel, stamping, shearing, drawing and heading can all be successfully performed. In addition, annealing can be performed on both grades between 1850 F and 2050 F, followed by rapid cooling. Furthermore, all common hot working methods are possible with 317 Stainless Steel and 317L Stainless Steel, between 2100 F and 2300 F.
Industries that use 317 Stainless Steel and 317L Stainless Steel include:
- Chemical
- Food processing
- Petrochemical
- Pharmaceutical
- Power generation
- Pulp and Paper
Products partially or completely constructed of 317 Stainless Steel and 317L Stainless Steel include:
