Stainless Steel 310S Cold Drawn vs 310S Solution Annealed
Stainless Steel · 310S temper comparison
310S Cold Drawn and 310S Solution Annealed are two conditions of the same stainless steel grade, 310S: Cold Drawn versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. 310S Cold Drawn is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 260 MPa (37.7 ksi) for 310S Solution Annealed, about 100% more; tensile strength follows at 760 MPa (110 ksi) vs 590 MPa (85.6 ksi). In exchange, 310S Solution Annealed is the more ductile: elongation 45% versus 25% for 310S Cold Drawn, and 310S Cold Drawn is harder (230 HB vs 160 HB).
310S Cold DrawnChoose it when strength drives the design.
310S Solution AnnealedChoose it when the part is bent, formed or impact-loaded.
310S Cold Drawn vs 310S Solution Annealed: 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.
