Stainless Steel SUS316J1 3/4H vs SUS316J1-CD
Stainless Steel · SUS316J1 temper comparison
SUS316J1 3/4H and SUS316J1-CD are two conditions of the same stainless steel grade, SUS316J1: 3/4H (three-quarter hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. SUS316J1 3/4H is the stronger of the two: yield strength 700 MPa (102 ksi) against 480 MPa (69.6 ksi) for SUS316J1-CD, about 46% more; tensile strength follows at 1,000 MPa (145 ksi) vs 700 MPa (102 ksi). In exchange, SUS316J1-CD is the more ductile: elongation 25% versus 8% for SUS316J1 3/4H, and SUS316J1 3/4H is harder (340 HB vs 210 HB). SUS316J1-CD runs hotter in service (350°C vs 300°C continuous). On the shop floor, SUS316J1-CD welds better (very good vs good).
SUS316J1 3/4HChoose it when strength drives the design.
SUS316J1-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
SUS316J1 3/4H vs SUS316J1-CD: 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.

SUS316J1 3/4H vs SUS316J1-CD — frequently asked
Is SUS316J1 3/4H stronger than SUS316J1-CD?
Yes. SUS316J1 3/4H has a typical yield strength of 700 MPa (102 ksi) against 480 MPa (69.6 ksi) for SUS316J1-CD — about 46% more. Tensile strength is 1,000 MPa (145 ksi) vs 700 MPa (102 ksi).
Which condition does FabDigit quote by default, 3/4H or CD?
Annealed is the default SUS316J1 condition in the FabDigit quote flow (neither 3/4H nor CD). 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, SUS316J1 3/4H or SUS316J1-CD?
SUS316J1-CD. Its machinability rates fair (36/100) against poor (31/100) for SUS316J1 3/4H; for welding the order is SUS316J1-CD first (very good, 72/100) then SUS316J1 3/4H (good, 62/100).
