Stainless Steel 310 Cold Drawn vs 310 Hot Rolled
Stainless Steel · 310 temper comparison
310 Cold Drawn and 310 Hot Rolled are two conditions of the same stainless steel grade, 310: Cold Drawn versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 310 Cold Drawn is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 340 MPa (49.3 ksi) for 310 Hot Rolled, about 62% more; tensile strength follows at 760 MPa (110 ksi) vs 690 MPa (100 ksi). In exchange, 310 Hot Rolled is the more ductile: elongation 40% versus 25% for 310 Cold Drawn, and 310 Cold Drawn is harder (220 HB vs 170 HB).
310 Cold DrawnChoose it when strength drives the design.
310 Hot RolledChoose it when the part is bent, formed or impact-loaded.
310 Cold Drawn vs 310 Hot Rolled: 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.

310 Cold Drawn vs 310 Hot Rolled — frequently asked
Is 310 Cold Drawn stronger than 310 Hot Rolled?
Yes. 310 Cold Drawn has a typical yield strength of 550 MPa (79.8 ksi) against 340 MPa (49.3 ksi) for 310 Hot Rolled — about 62% more. Tensile strength is 760 MPa (110 ksi) vs 690 MPa (100 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Hot Rolled?
Solution Annealed is the default 310 condition in the FabDigit quote flow (neither Cold Drawn nor Hot Rolled). 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.
When should I choose 310 Cold Drawn over 310 Hot Rolled?
Pick 310 Cold Drawn when strength drives the design. Pick 310 Hot Rolled when the part is bent, formed or impact-loaded.
