Refractory Metal Re (Pure Rhenium) Sintered vs Re (Pure Rhenium)-SR

Refractory Metal · Re (Pure Rhenium) temper comparison

Re (Pure Rhenium) Sintered and Re (Pure Rhenium)-SR are two conditions of the same refractory metal grade, Re (Pure Rhenium): Sintered versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Re (Pure Rhenium)-SR is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 450 MPa (65.3 ksi) for Re (Pure Rhenium) Sintered, about 144% more; tensile strength follows at 1,550 MPa (225 ksi) vs 800 MPa (116 ksi). Re (Pure Rhenium)-SR is the more ductile: elongation 12% versus 8% for Re (Pure Rhenium) Sintered, and Re (Pure Rhenium)-SR is harder (360 HB vs 285 HB). Re (Pure Rhenium)-SR is stiffer (460 GPa vs 430 GPa) and Re (Pure Rhenium) Sintered runs hotter in service (2,000°C vs 1,500°C continuous).

Re (Pure Rhenium) Sintered vs Re (Pure Rhenium)-SR — frequently asked

Is Re (Pure Rhenium)-SR stronger than Re (Pure Rhenium) Sintered?

Yes. Re (Pure Rhenium)-SR has a typical yield strength of 1,100 MPa (160 ksi) against 450 MPa (65.3 ksi) for Re (Pure Rhenium) Sintered — about 144% more. Tensile strength is 1,550 MPa (225 ksi) vs 800 MPa (116 ksi).

Which condition does FabDigit quote by default, Sintered or SR?

Annealed is the default Re (Pure Rhenium) condition in the FabDigit quote flow (neither Sintered nor SR). 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 Re (Pure Rhenium) Sintered over Re (Pure Rhenium)-SR?

Pick Re (Pure Rhenium) Sintered when the part sees heat. Pick Re (Pure Rhenium)-SR when strength drives the design, or when the part is bent, formed or impact-loaded.
