Titanium Grade 16 16H vs Grade 16 Annealed
Titanium · Grade 16 temper comparison
Grade 16 16H and Grade 16 Annealed are two conditions of the same titanium grade, Grade 16: 16H (grade 16H) versus Annealed. The chemistry is identical, so every difference below comes from the condition. Grade 16 16H is the stronger of the two: yield strength 400 MPa (58 ksi) against 380 MPa (55.1 ksi) for Grade 16 Annealed, about 5% more. In exchange, Grade 16 Annealed is the more ductile: elongation 28% versus 25% for Grade 16 16H, and Grade 16 16H is harder (160 HB vs 150 HB).
Grade 16 16HChoose it when strength drives the design.
Grade 16 AnnealedChoose it when the part is bent, formed or impact-loaded.
Grade 16 16H vs Grade 16 Annealed: 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 16 16H vs Grade 16 Annealed — frequently asked
Is Grade 16 16H stronger than Grade 16 Annealed?
Yes. Grade 16 16H has a typical yield strength of 400 MPa (58 ksi) against 380 MPa (55.1 ksi) for Grade 16 Annealed — about 5% more. Tensile strength is 500 MPa (72.5 ksi) vs 485 MPa (70.3 ksi).
Which condition does FabDigit quote by default, 16H or Annealed?
Annealed is the default Grade 16 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.
When should I choose Grade 16 16H over Grade 16 Annealed?
Pick Grade 16 16H when strength drives the design. Pick Grade 16 Annealed when the part is bent, formed or impact-loaded.
