Titanium Ti-6Al-4V ELI (AM, F3001)-HIP vs Ti-6Al-4V ELI (AM, F3001)-STA

Titanium · Ti-6Al-4V ELI (AM, F3001) temper comparison

Ti-6Al-4V ELI (AM, F3001)-HIP and Ti-6Al-4V ELI (AM, F3001)-STA are two conditions of the same titanium grade, Ti-6Al-4V ELI (AM, F3001): HIP (hot isostatic pressed) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. Ti-6Al-4V ELI (AM, F3001)-STA is the stronger of the two: yield strength 1,050 MPa (152 ksi) against 870 MPa (126 ksi) for Ti-6Al-4V ELI (AM, F3001)-HIP, about 21% more; tensile strength follows at 1,150 MPa (167 ksi) vs 960 MPa (139 ksi). In exchange, Ti-6Al-4V ELI (AM, F3001)-HIP is the more ductile: elongation 17% versus 10% for Ti-6Al-4V ELI (AM, F3001)-STA, and Ti-6Al-4V ELI (AM, F3001)-STA is harder (37 HRC vs 31 HRC).

Ti-6Al-4V ELI (AM, F3001)-HIP vs Ti-6Al-4V ELI (AM, F3001)-STA — frequently asked

Is Ti-6Al-4V ELI (AM, F3001)-STA stronger than Ti-6Al-4V ELI (AM, F3001)-HIP?

Yes. Ti-6Al-4V ELI (AM, F3001)-STA has a typical yield strength of 1,050 MPa (152 ksi) against 870 MPa (126 ksi) for Ti-6Al-4V ELI (AM, F3001)-HIP — about 21% more. Tensile strength is 1,150 MPa (167 ksi) vs 960 MPa (139 ksi).

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

SR is the default Ti-6Al-4V ELI (AM, F3001) condition in the FabDigit quote flow (neither HIP nor STA). 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, Ti-6Al-4V ELI (AM, F3001)-HIP or Ti-6Al-4V ELI (AM, F3001)-STA?

Ti-6Al-4V ELI (AM, F3001)-HIP, by a small margin. Both rate poor for machinability — 23/100 against 18/100 for Ti-6Al-4V ELI (AM, F3001)-STA.
