Refractory Metal Zr 704C-HIP vs Zr 704C-SR
Refractory Metal · Zr 704C temper comparison
Zr 704C-HIP and Zr 704C-SR are two conditions of the same refractory metal grade, Zr 704C: HIP (hot isostatic pressed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Zr 704C-HIP is the stronger of the two: yield strength 310 MPa (45 ksi) against 275 MPa (39.9 ksi) for Zr 704C-SR, about 13% more; tensile strength follows at 470 MPa (68.2 ksi) vs 435 MPa (63.1 ksi).

Zr 704C-HIP vs Zr 704C-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.

Zr 704C-HIP vs Zr 704C-SR — frequently asked
Is Zr 704C-HIP stronger than Zr 704C-SR?
Yes. Zr 704C-HIP has a typical yield strength of 310 MPa (45 ksi) against 275 MPa (39.9 ksi) for Zr 704C-SR — about 13% more. Tensile strength is 470 MPa (68.2 ksi) vs 435 MPa (63.1 ksi).
Which condition does FabDigit quote by default, HIP or SR?
F is the default Zr 704C 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.
When should I choose Zr 704C-HIP over Zr 704C-SR?
Pick Zr 704C-HIP when strength drives the design.
