Refractory Metal Mo (Grade 360)-CW vs Mo (Grade 360)-SR
Refractory Metal · Mo (Grade 360) temper comparison
Mo (Grade 360)-CW and Mo (Grade 360)-SR are two conditions of the same refractory metal grade, Mo (Grade 360): CW (cold worked) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Mo (Grade 360)-CW is the stronger of the two: yield strength 820 MPa (119 ksi) against 585 MPa (84.8 ksi) for Mo (Grade 360)-SR, about 40% more; tensile strength follows at 950 MPa (138 ksi) vs 760 MPa (110 ksi). In exchange, Mo (Grade 360)-SR is the more ductile: elongation 15% versus 6% for Mo (Grade 360)-CW, and Mo (Grade 360)-CW is harder (28 HRC vs 20 HRC). Mo (Grade 360)-SR runs hotter in service (1,100°C vs 900°C continuous).
Mo (Grade 360)-CWChoose it when strength drives the design.
Mo (Grade 360)-SRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Mo (Grade 360)-CW 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)-CW vs Mo (Grade 360)-SR — frequently asked
Is Mo (Grade 360)-CW stronger than Mo (Grade 360)-SR?
Yes. Mo (Grade 360)-CW has a typical yield strength of 820 MPa (119 ksi) against 585 MPa (84.8 ksi) for Mo (Grade 360)-SR — about 40% more. Tensile strength is 950 MPa (138 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, CW 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)-CW or Mo (Grade 360)-SR?
Mo (Grade 360)-SR, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for Mo (Grade 360)-CW.
