Steel Maraging 300 As Printed vs Maraging 300 Stress Relieved
Steel · Maraging 300 temper comparison
Maraging 300 As Printed and Maraging 300 Stress Relieved are two conditions of the same steel grade, Maraging 300: As Printed (as built (as printed)) versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. Maraging 300 Stress Relieved is the stronger of the two: yield strength 950 MPa (138 ksi) against 800 MPa (116 ksi) for Maraging 300 As Printed, about 19% more; tensile strength follows at 1,100 MPa (160 ksi) vs 1,010 MPa (146 ksi). In exchange, Maraging 300 As Printed is the more ductile: elongation 17% versus 14% for Maraging 300 Stress Relieved, and Maraging 300 Stress Relieved is harder (320 HB vs 300 HB). Maraging 300 As Printed conducts heat better (20 W/m·K vs 17 W/m·K).
Maraging 300 As PrintedChoose it when the part is bent, formed or impact-loaded.
Maraging 300 Stress RelievedChoose it when strength drives the design.
Maraging 300 As Printed vs Maraging 300 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 300 As Printed vs Maraging 300 Stress Relieved — frequently asked
Is Maraging 300 Stress Relieved stronger than Maraging 300 As Printed?
Yes. Maraging 300 Stress Relieved has a typical yield strength of 950 MPa (138 ksi) against 800 MPa (116 ksi) for Maraging 300 As Printed — about 19% more. Tensile strength is 1,100 MPa (160 ksi) vs 1,010 MPa (146 ksi).
Which condition does FabDigit quote by default, As Printed or Stress Relieved?
Annealed is the default Maraging 300 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.
When should I choose Maraging 300 As Printed over Maraging 300 Stress Relieved?
Pick Maraging 300 As Printed when the part is bent, formed or impact-loaded. Pick Maraging 300 Stress Relieved when strength drives the design.
