Stainless Steel SUS836L 1/2H vs SUS836L 1/4H
Stainless Steel · SUS836L temper comparison
SUS836L 1/2H and SUS836L 1/4H are two conditions of the same stainless steel grade, SUS836L: 1/2H (half hard) versus 1/4H (quarter hard). The chemistry is identical, so every difference below comes from the condition. SUS836L 1/2H is the stronger of the two: yield strength 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for SUS836L 1/4H, about 27% more; tensile strength follows at 950 MPa (138 ksi) vs 830 MPa (120 ksi). In exchange, SUS836L 1/4H is the more ductile: elongation 25% versus 15% for SUS836L 1/2H, and SUS836L 1/2H is harder (275 HB vs 238 HB). SUS836L 1/4H runs hotter in service (350°C vs 300°C continuous).
SUS836L 1/2HChoose it when strength drives the design.
SUS836L 1/4HChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
SUS836L 1/2H vs SUS836L 1/4H: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

SUS836L 1/2H vs SUS836L 1/4H — frequently asked
Is SUS836L 1/2H stronger than SUS836L 1/4H?
Yes. SUS836L 1/2H has a typical yield strength of 700 MPa (102 ksi) against 550 MPa (79.8 ksi) for SUS836L 1/4H — about 27% more. Tensile strength is 950 MPa (138 ksi) vs 830 MPa (120 ksi).
Which condition does FabDigit quote by default, 1/2H or 1/4H?
SA is the default SUS836L condition in the FabDigit quote flow (neither 1/2H nor 1/4H). 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 welds better, SUS836L 1/2H or SUS836L 1/4H?
SUS836L 1/4H. Its weldability rates good (65/100) against good (60/100) for SUS836L 1/2H.
