Stainless Steel 302 Annealed vs 302 Cold Drawn
Stainless Steel · 302 temper comparison
302 Annealed and 302 Cold Drawn are two conditions of the same stainless steel grade, 302: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 302 Cold Drawn is the stronger of the two: yield strength 690 MPa (100 ksi) against 275 MPa (39.9 ksi) for 302 Annealed, about 151% more; tensile strength follows at 860 MPa (125 ksi) vs 620 MPa (89.9 ksi). In exchange, 302 Annealed is the more ductile: elongation 55% versus 14% for 302 Cold Drawn, and 302 Cold Drawn is harder (250 HB vs 150 HB).
302 AnnealedChoose it when the part is bent, formed or impact-loaded.
302 Cold DrawnChoose it when strength drives the design.
302 Annealed vs 302 Cold Drawn: 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.
