Refractory Metal Pure Mo As Rolled vs Pure Mo Stress Relieved
Refractory Metal · Pure Mo temper comparison
Pure Mo As Rolled and Pure Mo Stress Relieved are two conditions of the same refractory metal grade, Pure Mo: As Rolled (hot rolled) versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. Pure Mo As Rolled is the stronger of the two: yield strength 590 MPa (85.6 ksi) against 450 MPa (65.3 ksi) for Pure Mo Stress Relieved, about 31% more; tensile strength follows at 700 MPa (102 ksi) vs 550 MPa (79.8 ksi). In exchange, Pure Mo Stress Relieved is the more ductile: elongation 20% versus 10% for Pure Mo As Rolled, and Pure Mo As Rolled is harder (250 HV vs 225 HV).
Pure Mo As RolledChoose it when strength drives the design.
Pure Mo Stress RelievedChoose it when the part is bent, formed or impact-loaded.
Pure Mo As Rolled vs Pure Mo Stress Relieved: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all refractory metal 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.
