Stainless Steel 310 Hot Rolled vs 310 Solution Annealed
Stainless Steel · 310 temper comparison
310 Hot Rolled and 310 Solution Annealed are two conditions of the same stainless steel grade, 310: Hot Rolled versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. 310 Hot Rolled is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 310 MPa (45 ksi) for 310 Solution Annealed, about 10% more; tensile strength follows at 690 MPa (100 ksi) vs 655 MPa (95 ksi). In exchange, 310 Solution Annealed is the more ductile: elongation 45% versus 40% for 310 Hot Rolled, and 310 Hot Rolled is harder (170 HB vs 150 HB).
310 Hot RolledChoose it when strength drives the design.
310 Solution AnnealedChoose it when the part is bent, formed or impact-loaded.
310 Hot Rolled vs 310 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.
