What is SUS317J2 Annealed?
SUS317J2 Annealed is SUS317J2 in the Annealed temper — standard supply condition for plate, sheet, pipe and bar where maximum corrosion resistance is required. SUS317J2 Annealed has a yield strength of 390 MPa (56.6 ksi) and a tensile strength of 720 MPa (104 ksi) — stronger than 54% of stainless steel grades. Elongation at break is 48% and the elastic modulus is 195 GPa (28.3 Msi). SUS317J2 Annealed has a density of 8 g/cm³ (0.289 lb/in³), heavier than 92% of stainless steel grades. It melts at 1,370°C (2,498 °F).

Working with SUS317J2 Annealed
Is SUS317J2 easy to machine?
Gummy and strongly work-hardening — use rigid setups, positive-rake carbide, heavy feeds, low-to-moderate speed and flood coolant; avoid dwelling.
Can SUS317J2 be welded?
Readily welded by GTAW/GMAW with over-alloyed filler (ER317L, ER385/904L or Ni-base 625); keep interpass low and heat input modest to avoid σ/χ phase, no PWHT normally required.
Can SUS317J2 be formed, bent or molded?
Cold forms well but needs ~50 % more press force than 304 and generous springback allowance; hot work at 1100–1200 °C followed by rapid cooling from solution temperature.
What surface finishes work on SUS317J2?
Pickle and passivate (or electropolish) after welding to restore the passive film; not anodizable, mechanical polishing to mirror finish is straightforward.

SUS317J2 Annealed — frequently asked
What is SUS317J2 Annealed used for?
SUS317J2 Annealed is typically used for seawater desalination, chemical processing and flue gas equipment. In short: most corrosion-resistant 317 variant; chloride-service austenitic; high strength, hard to form.
What is the yield strength of SUS317J2 Annealed?
SUS317J2 Annealed has a typical yield strength of 390 MPa (56.6 ksi) and a tensile strength of 720 MPa (104 ksi) — stronger than 54% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is SUS317J2 Annealed easy to machine?
Not especially — machinability is rated poor (30/100, worse than 70% of stainless steel grades). Gummy and strongly work-hardening — use rigid setups, positive-rake carbide, heavy feeds, low-to-moderate speed and flood coolant; avoid dwelling.
Can SUS317J2 Annealed be welded?
Yes — weldability is rated very good (70/100). Readily welded by GTAW/GMAW with over-alloyed filler (ER317L, ER385/904L or Ni-base 625); keep interpass low and heat input modest to avoid σ/χ phase, no PWHT normally required.
What surface finishes work on SUS317J2 Annealed?
Pickle and passivate (or electropolish) after welding to restore the passive film; not anodizable, mechanical polishing to mirror finish is straightforward.
Can SUS317J2 Annealed be formed, bent or molded?
Cold forms well but needs ~50 % more press force than 304 and generous springback allowance; hot work at 1100–1200 °C followed by rapid cooling from solution temperature.
What is the maximum service temperature of SUS317J2 Annealed?
SUS317J2 Annealed is rated for continuous use to about 550°C (1,022 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between SUS317J2 Annealed and SUS317J2-FH?
Annealed is the default condition — standard supply condition for plate, sheet, pipe and bar where maximum corrosion resistance is required. FH: maximum strength cold-worked strip or wire; forming is limited to simple bends. Yield strength is 390 MPa in Annealed versus 1,000 MPa in FH.
