Steel Maraging 250 As Printed vs Maraging 250 Stress Relieved
Steel · Maraging 250 temper comparison
Maraging 250 As Printed and Maraging 250 Stress Relieved are two conditions of the same steel grade, Maraging 250: As Printed (as built (as printed)) versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. Maraging 250 As Printed is the stronger of the two: yield strength 950 MPa (138 ksi) against 860 MPa (125 ksi) for Maraging 250 Stress Relieved, about 10% more; tensile strength follows at 1,130 MPa (164 ksi) vs 1,050 MPa (152 ksi). In exchange, Maraging 250 Stress Relieved is the more ductile: elongation 14% versus 12% for Maraging 250 As Printed, and Maraging 250 As Printed is harder (34 HRC vs 32 HRC). Maraging 250 Stress Relieved is stiffer (180 GPa vs 170 GPa) and Maraging 250 Stress Relieved conducts heat better (24 W/m·K vs 20 W/m·K).

Maraging 250 Stress RelievedChoose it when the part is bent, formed or impact-loaded.
Maraging 250 As Printed 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 As Printed vs Maraging 250 Stress Relieved — frequently asked
Is Maraging 250 As Printed stronger than Maraging 250 Stress Relieved?
Yes. Maraging 250 As Printed has a typical yield strength of 950 MPa (138 ksi) against 860 MPa (125 ksi) for Maraging 250 Stress Relieved — about 10% more. Tensile strength is 1,130 MPa (164 ksi) vs 1,050 MPa (152 ksi).
Which condition does FabDigit quote by default, As Printed or Stress Relieved?
Annealed is the default Maraging 250 condition in the FabDigit quote flow (neither As Printed 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 As Printed 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 As Printed; for welding the order is Maraging 250 Stress Relieved first (excellent, 85/100) then Maraging 250 As Printed (very good, 80/100).
