Stainless Steel 2507 Annealed vs 2507 Cold Drawn
Stainless Steel · 2507 temper comparison
2507 Annealed and 2507 Cold Drawn are two conditions of the same stainless steel grade, 2507: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. 2507 Cold Drawn is the stronger of the two: yield strength 780 MPa (113 ksi) against 610 MPa (88.5 ksi) for 2507 Annealed, about 28% more; tensile strength follows at 950 MPa (138 ksi) vs 870 MPa (126 ksi). In exchange, 2507 Annealed is the more ductile: elongation 30% versus 20% for 2507 Cold Drawn, and 2507 Cold Drawn is harder (310 HB vs 265 HB). On the shop floor, 2507 Annealed welds better (good vs fair).
2507 AnnealedChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
2507 Cold DrawnChoose it when strength drives the design.
2507 Annealed vs 2507 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.
