Stainless Steel SUS836L 1/4H vs SUS836L-AW

Stainless Steel · SUS836L temper comparison

SUS836L 1/4H and SUS836L-AW are two conditions of the same stainless steel grade, SUS836L: 1/4H (quarter hard) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. SUS836L 1/4H is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 330 MPa (47.9 ksi) for SUS836L-AW, about 67% more; tensile strength follows at 830 MPa (120 ksi) vs 620 MPa (89.9 ksi). In exchange, SUS836L-AW is the more ductile: elongation 35% versus 25% for SUS836L 1/4H, and SUS836L 1/4H is harder (238 HB vs 190 HB). SUS836L-AW runs hotter in service (400°C vs 350°C continuous).

SUS836L 1/4H vs SUS836L-AW — frequently asked

Is SUS836L 1/4H stronger than SUS836L-AW?

Yes. SUS836L 1/4H has a typical yield strength of 550 MPa (79.8 ksi) against 330 MPa (47.9 ksi) for SUS836L-AW — about 67% more. Tensile strength is 830 MPa (120 ksi) vs 620 MPa (89.9 ksi).

Which condition does FabDigit quote by default, 1/4H or AW?

SA is the default SUS836L condition in the FabDigit quote flow (neither 1/4H nor AW). 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, SUS836L 1/4H or SUS836L-AW?

SUS836L 1/4H, by a small margin. Both rate poor for machinability — 30/100 against 24/100 for SUS836L-AW; for welding the order is SUS836L-AW first (very good, 70/100) then SUS836L 1/4H (good, 65/100).
