Stainless Steel 301 Annealed vs 301 Cold Rolled
Stainless Steel · 301 temper comparison
301 Annealed and 301 Cold Rolled are two conditions of the same stainless steel grade, 301: Annealed versus Cold Rolled. The chemistry is identical, so every difference below comes from the condition. 301 Cold Rolled is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 280 MPa (40.6 ksi) for 301 Annealed, about 104% more; tensile strength follows at 900 MPa (131 ksi) vs 760 MPa (110 ksi). In exchange, 301 Annealed is the more ductile: elongation 55% versus 25% for 301 Cold Rolled, and 301 Cold Rolled is harder (270 HB vs 165 HB). 301 Annealed runs hotter in service (760°C vs 425°C continuous).
301 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
301 Cold RolledChoose it when strength drives the design.
301 Annealed vs 301 Cold 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.

301 Annealed vs 301 Cold Rolled — frequently asked
Is 301 Cold Rolled stronger than 301 Annealed?
Yes. 301 Cold Rolled has a typical yield strength of 570 MPa (82.7 ksi) against 280 MPa (40.6 ksi) for 301 Annealed — about 104% more. Tensile strength is 900 MPa (131 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Rolled?
Cold Rolled is the default 301 condition in the FabDigit quote flow. 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, 301 Annealed or 301 Cold Rolled?
301 Annealed, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for 301 Cold Rolled; for welding the order is 301 Annealed first (very good, 70/100) then 301 Cold Rolled (good, 65/100).
