Stainless Steel SUS317J2 Annealed vs SUS317J2-CD
Stainless Steel · SUS317J2 temper comparison
SUS317J2 Annealed and SUS317J2-CD are two conditions of the same stainless steel grade, SUS317J2: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. SUS317J2-CD is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 390 MPa (56.6 ksi) for SUS317J2 Annealed, about 46% more; tensile strength follows at 830 MPa (120 ksi) vs 720 MPa (104 ksi). In exchange, SUS317J2 Annealed is the more ductile: elongation 48% versus 30% for SUS317J2-CD, and SUS317J2-CD is harder (240 HB vs 180 HB). SUS317J2 Annealed runs hotter in service (550°C vs 400°C continuous).
SUS317J2 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
SUS317J2-CDChoose it when strength drives the design.
SUS317J2 Annealed vs SUS317J2-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.
