  • Stainless Steel grades 317 and 317L Bar Round Hex Bright

    Pacific Stainless & Alloys inventory now includes stainless steel 317L (UNS S31703) in stainless plate, round bar, processed flat bar and tubular products.

  • General Properties
  • Alloy 317L is a molybdenum containing, low carbon austenitic stainless steel with increased additions of chromium, nickel, and molybdenum for better corrosion resistance and increased resistance to chemical attack for sulfurous, acetic, formic, citric, and tartaric acids. Due to its low carbon content, 317L also provides resistance to sensitization when welded and higher creep, stress to rupture, and tensile strength at elevated temperatures. It is non-magnetic in the annealed condition but may become slightly magnetic after welding.
  • Applications
  • Alloy 317L is commonly used to handle sulfur, pulp liquor, acid dyestuffs, acetylating and nitrating mixtures, bleaching solutions, severe coal and oil, and many chemical compounds. Some other applications that use alloy 317L include:
  • Paper and pulp handling equipment
  • Chemical and petrochemical processing equipment
  • Condensers in fossil and nuclear fueled power generation stations
  • Food processing equipment
  • Textile equipment
  • Standards – Alloy 317L
  • ASTM/ASME: UNS N08020
  • EURONORM: FeMi35Cr20Cu4Mo2
  • DIN: 2.4660

    Steel Bar Specifications

    Primary Elements: Grade 317 and 317L are alloys primarily comprised of between 18 and 20 percent Chromium, 11 to 15 percent Nickel, 3 to 4 percent Molybdenum, 2 percent Manganese, along with trace amounts of Carbon, Phosphorus, Sulfur, and Silicon, with the balance being Iron. The significant difference between Stainless Steel grades 317 and 317L is that 317L is the extra low carbon variation of 317 for welded structures.

    Features: The design features and advantages of Stainless Steel grades 317 and 317L include increased strength and corrosion resistance (especially in harsh environments); higher tensile strength, stress-to-rupture and creep than other stainless steel grades; and, resistance to crevice corrosion and pitting, making 317L the cost-effective choice for use in a wide range of corrosive conditions. Specifically, both Stainless Steel grades 317 and 317L resist pitting in acetic and phosphoric acids. With respect to cold working of Stainless Steel grades 317 and 317L, stamping, shearing, drawing and heading can all be successfully performed. In addition, annealing can be performed on 317 and 317L between 1850 and 2050 Degrees Fahrenheit (1010 and 1121 Degrees Celsius), followed by rapid cooling. Furthermore, all common hot working methods are possible with Stainless Steel grades 317 and 317L, between 2100 and 2300 Degrees Fahrenheit (1149 and 1260 Degrees Celsius).
