Titanium Grade 2H F-2H vs Grade 2H-HR
Titanium · Grade 2H temper comparison
Grade 2H F-2H and Grade 2H-HR are two conditions of the same titanium grade, Grade 2H: F-2H (forged and annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Grade 2H-HR is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 345 MPa (50 ksi) for Grade 2H F-2H, about 12% more; tensile strength follows at 490 MPa (71.1 ksi) vs 455 MPa (66 ksi). Grade 2H-HR is harder — 175 HB against 160 HB for Grade 2H F-2H — which matters for wear surfaces and threads.
Grade 2H-HRChoose it when strength drives the design, or when surface hardness matters.
Grade 2H F-2H vs Grade 2H-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.

Grade 2H F-2H vs Grade 2H-HR — frequently asked
Is Grade 2H-HR stronger than Grade 2H F-2H?
Yes. Grade 2H-HR has a typical yield strength of 385 MPa (55.8 ksi) against 345 MPa (50 ksi) for Grade 2H F-2H — about 12% more. Tensile strength is 490 MPa (71.1 ksi) vs 455 MPa (66 ksi).
Which condition does FabDigit quote by default, F-2H or HR?
ANN is the default Grade 2H condition in the FabDigit quote flow (neither F-2H 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 Grade 2H F-2H over Grade 2H-HR?
Pick Grade 2H-HR when strength drives the design, or when surface hardness matters.
