317/317L Stainless Steel Bar
UNS S31700/S31703 (Dual Certified)
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 Stainless Steel 317/317L Dual Certified is the low carbon content version of Stainless Steel 317 for welded structures.
Features and advantages of both Stainless Steel 317 and 317/317L Dual Certified 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 Stainless Steel 317 and 317/317L Dual Certified, 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 Stainless Steel 317 and 317/317L Dual Certified, between 2100 F and 2300 F.
