Working with SUS316J1L-H
Is SUS316J1L easy to machine?
Work-hardens strongly and chips smear on the cutting edge: use sharp high positive-rake tooling, rigid clamping, lower cutting speed with heavy feed and generous coolant, and avoid air-cutting passes that leave a hardened skin.
Can SUS316J1L be welded?
The extra-low carbon means no post-weld solution treatment is needed after GTAW, GMAW or resistance welding; use ER316L filler, or a matching Cu-bearing wire where full corrosion match is required, control interpass temperature and pickle/passivate after welding.
Can SUS316J1L be formed, bent or molded?
The copper addition lowers the work-hardening rate, so cold heading, deep drawing and spinning are better than plain 316L; use an interstage anneal on severely drawn parts to restore ductility.
What surface finishes work on SUS316J1L?
Available as 2B, BA, No.4 brushed or No.8 mirror polish; nitric-acid pickling and passivation or electropolishing restores best corrosion resistance. Not anodisable.

SUS316J1L-H — frequently asked
What is SUS316J1L-H used for?
SUS316J1L-H is typically used for welded chemical tanks, food processing equipment, kitchenware and architectural panels. In short: weldable copper-bearing 316; no post-weld solution anneal; top-tier deep-draw formability.
What is the yield strength of SUS316J1L-H?
SUS316J1L-H has a typical yield strength of 830 MPa (120 ksi) and a tensile strength of 1,000 MPa (145 ksi) — stronger than 97% of stainless steel grades. Strength varies by condition: see the 7 listed tempers.
Is SUS316J1L-H easy to machine?
Not especially — machinability is rated poor (32/100, worse than 62% of stainless steel grades). Work-hardens strongly and chips smear on the cutting edge: use sharp high positive-rake tooling, rigid clamping, lower cutting speed with heavy feed and generous coolant, and avoid air-cutting passes that leave a hardened skin.
Can SUS316J1L-H be welded?
Yes — weldability is rated very good (70/100). The extra-low carbon means no post-weld solution treatment is needed after GTAW, GMAW or resistance welding; use ER316L filler, or a matching Cu-bearing wire where full corrosion match is required, control interpass temperature and pickle/passivate after welding.
What surface finishes work on SUS316J1L-H?
Available as 2B, BA, No.4 brushed or No.8 mirror polish; nitric-acid pickling and passivation or electropolishing restores best corrosion resistance. Not anodisable.
Can SUS316J1L-H be formed, bent or molded?
The copper addition lowers the work-hardening rate, so cold heading, deep drawing and spinning are better than plain 316L; use an interstage anneal on severely drawn parts to restore ductility.
What is the maximum service temperature of SUS316J1L-H?
SUS316J1L-H is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between SUS316J1L Annealed and SUS316J1L-H?
Annealed is the default condition — default stock condition after solution annealing at 1010–1150 °C and water quench: best corrosion resistance and formability for welded vessels, deep drawing and cold-heading blanks. H: choose full-hard cold-rolled strip for spring contacts and blade-like thin parts at 1000 MPa tensile; at 8 % elongation there is almost no forming margin left. Yield strength is 250 MPa in Annealed versus 830 MPa in H.
