Titanium Ti Grade 2 AM-LPBF vs Ti Grade 2-HR
Titanium · Ti Grade 2 temper comparison
Ti Grade 2 AM-LPBF and Ti Grade 2-HR are two conditions of the same titanium grade, Ti Grade 2: AM-LPBF (additively manufactured (L-PBF) as-built CP-Ti Grade 2 powder) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Ti Grade 2 AM-LPBF is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 370 MPa (53.7 ksi) for Ti Grade 2-HR, about 54% more; tensile strength follows at 690 MPa (100 ksi) vs 470 MPa (68.2 ksi). In exchange, Ti Grade 2-HR is the more ductile: elongation 22% versus 18% for Ti Grade 2 AM-LPBF, and Ti Grade 2 AM-LPBF is harder (209 HB vs 160 HB).
Ti Grade 2 AM-LPBFChoose it when strength drives the design.
Ti Grade 2-HRChoose it when the part is bent, formed or impact-loaded.
Ti Grade 2 AM-LPBF vs Ti Grade 2-HR: 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.

Ti Grade 2 AM-LPBF vs Ti Grade 2-HR — frequently asked
Is Ti Grade 2 AM-LPBF stronger than Ti Grade 2-HR?
Yes. Ti Grade 2 AM-LPBF has a typical yield strength of 570 MPa (82.7 ksi) against 370 MPa (53.7 ksi) for Ti Grade 2-HR — about 54% more. Tensile strength is 690 MPa (100 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, AM-LPBF or HR?
Annealed is the default Ti Grade 2 condition in the FabDigit quote flow (neither AM-LPBF nor HR). 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 Ti Grade 2 AM-LPBF over Ti Grade 2-HR?
Pick Ti Grade 2 AM-LPBF when strength drives the design. Pick Ti Grade 2-HR when the part is bent, formed or impact-loaded.
