Working with SUS316J1 Annealed
Is SUS316J1 easy to machine?
Gummy and work-hardening like 316: use rigid setups, sharp positive-rake carbide, heavy positive feed, 60–110 m/min with flood coolant, and never dwell or rub.
Can SUS316J1 be welded?
Weld with 316L/ER316L (or matching Cu-bearing filler for full corrosion match), low heat input and interpass <150 °C; the Cu addition raises hot-cracking sensitivity so keep a small amount of delta ferrite and avoid heavy restraint.
Can SUS316J1 be formed, bent or molded?
Excellent deep-drawing and cold-heading behaviour — lower work hardening than 304/316 allows deeper draws with fewer interstage anneals; use chlorine-free drawing lubricants and Cr-free tooling coatings to avoid galling.
What surface finishes work on SUS316J1?
Takes BA and No.8 mirror polish readily for tableware; passivate in nitric or citric acid after machining/welding, electropolish for hygiene service; not anodisable, PVD colouring works well.
SUS316J1 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

SUS316J1 Annealed — frequently asked
What is SUS316J1 Annealed used for?
SUS316J1 Annealed is typically used for kitchen utensils, tableware, chemical equipment linings and architectural fittings. In short: best-forming 316 variant; copper-bearing JIS grade; limited non-Japanese stock.
What is the yield strength of SUS316J1 Annealed?
SUS316J1 Annealed has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 550 MPa (79.8 ksi) — weaker than 91% of stainless steel grades. Strength varies by condition: see the 7 listed tempers.
Is SUS316J1 Annealed easy to machine?
Not especially — machinability is rated poor (32/100, worse than 62% of stainless steel grades). Gummy and work-hardening like 316: use rigid setups, sharp positive-rake carbide, heavy positive feed, 60–110 m/min with flood coolant, and never dwell or rub.
Can SUS316J1 Annealed be welded?
Yes — weldability is rated very good (78/100). Weld with 316L/ER316L (or matching Cu-bearing filler for full corrosion match), low heat input and interpass <150 °C; the Cu addition raises hot-cracking sensitivity so keep a small amount of delta ferrite and avoid heavy restraint.
What surface finishes work on SUS316J1 Annealed?
Takes BA and No.8 mirror polish readily for tableware; passivate in nitric or citric acid after machining/welding, electropolish for hygiene service; not anodisable, PVD colouring works well.
Can SUS316J1 Annealed be formed, bent or molded?
Excellent deep-drawing and cold-heading behaviour — lower work hardening than 304/316 allows deeper draws with fewer interstage anneals; use chlorine-free drawing lubricants and Cr-free tooling coatings to avoid galling.
What is the maximum service temperature of SUS316J1 Annealed?
SUS316J1 Annealed is rated for continuous use to about 800°C (1,472 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between SUS316J1 Annealed and SUS316J1-H?
Annealed is the default condition — default stock condition for sheet, plate, bar and tube; maximum ductility for deep drawing and best corrosion resistance. H: maximum strength thin strip/wire for springs, blades and flat stock; essentially no formability beyond flat blanking. Yield strength is 250 MPa in Annealed versus 850 MPa in H.
