Refractory Metal Zr 705C-F vs Zr 705C-HIP

Refractory Metal · Zr 705C temper comparison

Zr 705C-F and Zr 705C-HIP are two conditions of the same refractory metal grade, Zr 705C: F (as fabricated) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. Both yield at about 386 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus hot isostatic pressed). Zr 705C-HIP is the more ductile: elongation 16% versus 13% for Zr 705C-F.

Zr 705C-F vs Zr 705C-HIP — frequently asked

What is the difference between Zr 705C-F and Zr 705C-HIP?

Zr 705C-F and Zr 705C-HIP are two conditions of the same refractory metal grade, Zr 705C: F (as fabricated) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. Both yield at about 386 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus hot isostatic pressed).

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

F is the default Zr 705C 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 welds better, Zr 705C-F or Zr 705C-HIP?

Zr 705C-HIP. Its weldability rates good (68/100) against good (62/100) for Zr 705C-F.
