Titanium Ti-6Al-4V ELI (Grade 23) AM Powder-HIP vs Ti-6Al-4V ELI (Grade 23) AM Powder-SR
Titanium · Ti-6Al-4V ELI (Grade 23) AM Powder temper comparison
Ti-6Al-4V ELI (Grade 23) AM Powder-HIP and Ti-6Al-4V ELI (Grade 23) AM Powder-SR are two conditions of the same titanium grade, Ti-6Al-4V ELI (Grade 23) AM Powder: HIP (hot isostatic pressed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Ti-6Al-4V ELI (Grade 23) AM Powder-SR is the stronger of the two: yield strength 1,010 MPa (146 ksi) against 880 MPa (128 ksi) for Ti-6Al-4V ELI (Grade 23) AM Powder-HIP, about 15% more; tensile strength follows at 1,100 MPa (160 ksi) vs 970 MPa (141 ksi). In exchange, Ti-6Al-4V ELI (Grade 23) AM Powder-HIP is the more ductile: elongation 17% versus 13% for Ti-6Al-4V ELI (Grade 23) AM Powder-SR, and Ti-6Al-4V ELI (Grade 23) AM Powder-SR is harder (35 HRC vs 32 HRC).
Ti-6Al-4V ELI (Grade 23) AM Powder-HIPChoose it when the part is bent, formed or impact-loaded.
Ti-6Al-4V ELI (Grade 23) AM Powder-SRChoose it when strength drives the design.
Ti-6Al-4V ELI (Grade 23) AM Powder-HIP vs Ti-6Al-4V ELI (Grade 23) AM Powder-SR: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium 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.
