Steel Maraging 250 Cold Drawn vs Maraging 250 Stress Relieved
Steel · Maraging 250 temper comparison
Maraging 250 Cold Drawn and Maraging 250 Stress Relieved are two conditions of the same steel grade, Maraging 250: Cold Drawn versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. Maraging 250 Cold Drawn is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 860 MPa (125 ksi) for Maraging 250 Stress Relieved, about 16% more; tensile strength follows at 1,150 MPa (167 ksi) vs 1,050 MPa (152 ksi). In exchange, Maraging 250 Stress Relieved is the more ductile: elongation 14% versus 10% for Maraging 250 Cold Drawn, and Maraging 250 Cold Drawn is harder (325 HB vs 305 HB). On the shop floor, Maraging 250 Stress Relieved welds better (excellent vs very good).
Maraging 250 Cold DrawnChoose it when strength drives the design.
Maraging 250 Stress RelievedChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
Maraging 250 Cold Drawn vs Maraging 250 Stress Relieved: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all 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.

Maraging 250 Cold Drawn vs Maraging 250 Stress Relieved — frequently asked
Is Maraging 250 Cold Drawn stronger than Maraging 250 Stress Relieved?
Yes. Maraging 250 Cold Drawn has a typical yield strength of 1,000 MPa (145 ksi) against 860 MPa (125 ksi) for Maraging 250 Stress Relieved — about 16% more. Tensile strength is 1,150 MPa (167 ksi) vs 1,050 MPa (152 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Stress Relieved?
Annealed is the default Maraging 250 condition in the FabDigit quote flow (neither Cold Drawn nor Stress Relieved). 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, Maraging 250 Cold Drawn or Maraging 250 Stress Relieved?
Maraging 250 Stress Relieved, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for Maraging 250 Cold Drawn; for welding the order is Maraging 250 Stress Relieved first (excellent, 85/100) then Maraging 250 Cold Drawn (very good, 75/100).
