Type 317L Stainless Steel (UNS 31703) is a low carbon austenitic chromium-nickel stainless steel that can be used in applications where it is not possible to anneal after welding and where maximum corrosion resistance is required. It provides good oxidation resistance in intermittent service to 1600°F and in continuous service to 1700°F.
Ultimate Tensile Strength: 75 KSI min (515 MPa min)
Yield Strength: (0.2% Offset) 30 KSI min (205 MPa min)
Elongation: 35% min
Hardness: Rb 95 max
Type 317L Stainless Steel can be cold rolled to tempers. Contact Ulbrich Technical Services for more details.
See NACE (National Association of Corrosion Engineers) for recommendations.
# 1 –Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
# 2D – Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
# 2B –Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA Bright annealed cold rolled and bright annealed
#CBA Course bright annealed cold rolled matte finish and bright anneal
#2 Cold Rolled
# 2BA – Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.
Polished - Various grit finish for specific polish finished requirements
Type 317L Stainless Steel can be readily formed and drawn.
Type 317L Stainless Steel is non hardenable by heat treatment and can only be hardened by cold working.
