Refractory Metal S-200F-HIP vs S-200F-SR

Refractory Metal · S-200F temper comparison

S-200F-HIP and S-200F-SR are two conditions of the same refractory metal grade, S-200F: HIP (hot isostatic pressed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. S-200F-HIP is the stronger of the two: yield strength 296 MPa (42.9 ksi) against 200 MPa (29 ksi) for S-200F-SR, about 48% more; tensile strength follows at 414 MPa (60 ksi) vs 330 MPa (47.9 ksi). In exchange, S-200F-SR is the more ductile: elongation 4% versus 3.5% for S-200F-HIP, and S-200F-HIP is harder (165 HB vs 140 HB).

S-200F-HIPChoose it when strength drives the design.

S-200F-SRChoose it when the part is bent, formed or impact-loaded.

S-200F-HIP vs S-200F-SR — frequently asked

Is S-200F-HIP stronger than S-200F-SR?

Yes. S-200F-HIP has a typical yield strength of 296 MPa (42.9 ksi) against 200 MPa (29 ksi) for S-200F-SR — about 48% more. Tensile strength is 414 MPa (60 ksi) vs 330 MPa (47.9 ksi).

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

HP is the default S-200F condition in the FabDigit quote flow (neither HIP 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.

Which is easier to machine, S-200F-HIP or S-200F-SR?

S-200F-SR. Its machinability rates fair (38/100) against poor (33/100) for S-200F-HIP.
