Titanium Ti Grade 13-AW vs Ti Grade 13-HR
Titanium · Ti Grade 13 temper comparison
Ti Grade 13-AW and Ti Grade 13-HR are two conditions of the same titanium grade, Ti Grade 13: AW (as-welded deposit) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Both yield at about 220 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as-welded deposit versus hot rolled). Ti Grade 13-HR is the more ductile: elongation 28% versus 22% for Ti Grade 13-AW, and Ti Grade 13-AW is harder (135 HB vs 125 HB).
Ti Grade 13-HRChoose it when the part is bent, formed or impact-loaded.
Ti Grade 13-AW vs Ti Grade 13-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 13-AW vs Ti Grade 13-HR — frequently asked
What is the difference between Ti Grade 13-AW and Ti Grade 13-HR?
Ti Grade 13-AW and Ti Grade 13-HR are two conditions of the same titanium grade, Ti Grade 13: AW (as-welded deposit) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. Both yield at about 220 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as-welded deposit versus hot rolled).
Which condition does FabDigit quote by default, AW or HR?
Annealed is the default Ti Grade 13 condition in the FabDigit quote flow (neither AW 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 13-AW over Ti Grade 13-HR?
Pick Ti Grade 13-HR when the part is bent, formed or impact-loaded.
