Refractory Metal Mo-47.5Re-AW vs Mo-47.5Re-CW

Refractory Metal · Mo-47.5Re temper comparison

Mo-47.5Re-AW and Mo-47.5Re-CW are two conditions of the same refractory metal grade, Mo-47.5Re: AW (as-welded deposit) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. Mo-47.5Re-CW is the stronger of the two: yield strength 1,600 MPa (232 ksi) against 520 MPa (75.4 ksi) for Mo-47.5Re-AW, about 3.1 times as much; tensile strength follows at 1,800 MPa (261 ksi) vs 900 MPa (131 ksi). In exchange, Mo-47.5Re-AW is the more ductile: elongation 14% versus 5% for Mo-47.5Re-CW, and Mo-47.5Re-CW is harder (47 HRC vs 27 HRC). Mo-47.5Re-AW runs hotter in service (2,000°C vs 1,100°C continuous). On the shop floor, Mo-47.5Re-AW welds better (very good vs good).

Mo-47.5Re-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Mo-47.5Re-CWChoose it when strength drives the design.

Mo-47.5Re-AW vs Mo-47.5Re-CW — frequently asked

Is Mo-47.5Re-CW stronger than Mo-47.5Re-AW?

Yes. Mo-47.5Re-CW has a typical yield strength of 1,600 MPa (232 ksi) against 520 MPa (75.4 ksi) for Mo-47.5Re-AW — about 3.1 times as much. Tensile strength is 1,800 MPa (261 ksi) vs 900 MPa (131 ksi).

Which condition does FabDigit quote by default, AW or CW?

SR is the default Mo-47.5Re condition in the FabDigit quote flow (neither AW nor CW). 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-47.5Re-AW or Mo-47.5Re-CW?

Mo-47.5Re-AW, by a small margin. Both rate poor for machinability — 22/100 against 15/100 for Mo-47.5Re-CW; for welding the order is Mo-47.5Re-AW first (very good, 75/100) then Mo-47.5Re-CW (good, 65/100).
