Steel Maraging 250 Annealed vs Maraging 250 Cold Drawn
Steel · Maraging 250 temper comparison
Maraging 250 Annealed and Maraging 250 Cold Drawn are two conditions of the same steel grade, Maraging 250: Annealed versus Cold Drawn. 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 810 MPa (117 ksi) for Maraging 250 Annealed, about 23% more; tensile strength follows at 1,150 MPa (167 ksi) vs 1,010 MPa (146 ksi). In exchange, Maraging 250 Annealed is the more ductile: elongation 18% versus 10% for Maraging 250 Cold Drawn, and Maraging 250 Cold Drawn is harder (325 HB vs 300 HB).

Maraging 250 Cold DrawnChoose it when strength drives the design.
Maraging 250 Annealed vs Maraging 250 Cold Drawn: 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 Annealed vs Maraging 250 Cold Drawn — frequently asked
Is Maraging 250 Cold Drawn stronger than Maraging 250 Annealed?
Yes. Maraging 250 Cold Drawn has a typical yield strength of 1,000 MPa (145 ksi) against 810 MPa (117 ksi) for Maraging 250 Annealed — about 23% more. Tensile strength is 1,150 MPa (167 ksi) vs 1,010 MPa (146 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Annealed is the default Maraging 250 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, Maraging 250 Annealed or Maraging 250 Cold Drawn?
Maraging 250 Annealed, 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 Annealed first (very good, 80/100) then Maraging 250 Cold Drawn (very good, 75/100).
