Stainless Steel SUS316J1L 1/2H vs SUS316J1L-HR

Stainless Steel · SUS316J1L temper comparison

SUS316J1L 1/2H and SUS316J1L-HR are two conditions of the same stainless steel grade, SUS316J1L: 1/2H (half hard) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. SUS316J1L 1/2H is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 245 MPa (35.5 ksi) for SUS316J1L-HR, about 112% more; tensile strength follows at 780 MPa (113 ksi) vs 540 MPa (78.3 ksi). In exchange, SUS316J1L-HR is the more ductile: elongation 52% versus 18% for SUS316J1L 1/2H, and SUS316J1L 1/2H is harder (245 HB vs 155 HB). SUS316J1L-HR runs hotter in service (500°C vs 350°C continuous).

SUS316J1L 1/2H vs SUS316J1L-HR — frequently asked

Is SUS316J1L 1/2H stronger than SUS316J1L-HR?

Yes. SUS316J1L 1/2H has a typical yield strength of 520 MPa (75.4 ksi) against 245 MPa (35.5 ksi) for SUS316J1L-HR — about 112% more. Tensile strength is 780 MPa (113 ksi) vs 540 MPa (78.3 ksi).

Which condition does FabDigit quote by default, 1/2H or HR?

Annealed is the default SUS316J1L condition in the FabDigit quote flow (neither 1/2H nor HR). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, SUS316J1L 1/2H or SUS316J1L-HR?

SUS316J1L 1/2H, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for SUS316J1L-HR; for welding the order is SUS316J1L-HR first (excellent, 88/100) then SUS316J1L 1/2H (very good, 80/100).
