Stainless Steel 2507 Annealed vs 2507 Cold Worked
Stainless Steel · 2507 temper comparison
2507 Annealed and 2507 Cold Worked are two conditions of the same stainless steel grade, 2507: Annealed versus Cold Worked. The chemistry is identical, so every difference below comes from the condition. 2507 Cold Worked is the stronger of the two: yield strength 850 MPa (123 ksi) against 610 MPa (88.5 ksi) for 2507 Annealed, about 39% more; tensile strength follows at 1,000 MPa (145 ksi) vs 870 MPa (126 ksi). In exchange, 2507 Annealed is the more ductile: elongation 30% versus 18% for 2507 Cold Worked, and 2507 Cold Worked is harder (330 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 WorkedChoose it when strength drives the design.
2507 Annealed vs 2507 Cold Worked: 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.

2507 Annealed vs 2507 Cold Worked — frequently asked
Is 2507 Cold Worked stronger than 2507 Annealed?
Yes. 2507 Cold Worked has a typical yield strength of 850 MPa (123 ksi) against 610 MPa (88.5 ksi) for 2507 Annealed — about 39% more. Tensile strength is 1,000 MPa (145 ksi) vs 870 MPa (126 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Worked?
Solution Annealed is the default 2507 condition in the FabDigit quote flow (neither Annealed nor Cold Worked). 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 welds better, 2507 Annealed or 2507 Cold Worked?
2507 Annealed. Its weldability rates good (60/100) against fair (45/100) for 2507 Cold Worked.
