Refractory Metal Mo (Grade 360) SINT vs Mo (Grade 360)-SR
Refractory Metal · Mo (Grade 360) temper comparison
Mo (Grade 360) SINT and Mo (Grade 360)-SR are two conditions of the same refractory metal grade, Mo (Grade 360): SINT (sintered) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Mo (Grade 360)-SR is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 250 MPa (36.3 ksi) for Mo (Grade 360) SINT, about 134% more; tensile strength follows at 760 MPa (110 ksi) vs 350 MPa (50.8 ksi). Mo (Grade 360)-SR is the more ductile: elongation 15% versus 3% for Mo (Grade 360) SINT, and Mo (Grade 360)-SR is harder (230 HV vs 150 HV). Mo (Grade 360) SINT is lighter (9.9 g/cm³ vs 10.22 g/cm³ for Mo (Grade 360)-SR) and Mo (Grade 360)-SR is stiffer (320 GPa vs 280 GPa).
Mo (Grade 360) SINTChoose it when weight is the constraint, or when the part sees heat.
Mo (Grade 360)-SRChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Mo (Grade 360) SINT vs Mo (Grade 360)-SR: 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.

Mo (Grade 360) SINT vs Mo (Grade 360)-SR — frequently asked
Is Mo (Grade 360)-SR stronger than Mo (Grade 360) SINT?
Yes. Mo (Grade 360)-SR has a typical yield strength of 585 MPa (84.8 ksi) against 250 MPa (36.3 ksi) for Mo (Grade 360) SINT — about 134% more. Tensile strength is 760 MPa (110 ksi) vs 350 MPa (50.8 ksi).
Which condition does FabDigit quote by default, SINT or SR?
SR is the default Mo (Grade 360) 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, Mo (Grade 360) SINT or Mo (Grade 360)-SR?
Mo (Grade 360) SINT, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for Mo (Grade 360)-SR.
