Titanium Ti-13V-11Cr-3Al-CWA vs Ti-13V-11Cr-3Al-ST
Titanium · Ti-13V-11Cr-3Al temper comparison
Ti-13V-11Cr-3Al-CWA and Ti-13V-11Cr-3Al-ST are two conditions of the same titanium grade, Ti-13V-11Cr-3Al: CWA (cold worked and aged) versus ST (solution annealed). The chemistry is identical, so every difference below comes from the condition. Ti-13V-11Cr-3Al-CWA is the stronger of the two: yield strength 1,330 MPa (193 ksi) against 860 MPa (125 ksi) for Ti-13V-11Cr-3Al-ST, about 55% more; tensile strength follows at 1,400 MPa (203 ksi) vs 930 MPa (135 ksi). In exchange, Ti-13V-11Cr-3Al-ST is the more ductile: elongation 16% versus 4% for Ti-13V-11Cr-3Al-CWA, and Ti-13V-11Cr-3Al-CWA is harder (44 HRC vs 31 HRC). Ti-13V-11Cr-3Al-CWA is stiffer (115 GPa vs 102 GPa) and Ti-13V-11Cr-3Al-CWA runs hotter in service (315°C vs 260°C continuous). On the shop floor, Ti-13V-11Cr-3Al-ST welds better (good vs poor).
Ti-13V-11Cr-3Al-CWAChoose it when strength drives the design, or when the part sees heat.
Ti-13V-11Cr-3Al-STChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
Ti-13V-11Cr-3Al-CWA vs Ti-13V-11Cr-3Al-ST: 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-13V-11Cr-3Al-CWA vs Ti-13V-11Cr-3Al-ST — frequently asked
Is Ti-13V-11Cr-3Al-CWA stronger than Ti-13V-11Cr-3Al-ST?
Yes. Ti-13V-11Cr-3Al-CWA has a typical yield strength of 1,330 MPa (193 ksi) against 860 MPa (125 ksi) for Ti-13V-11Cr-3Al-ST — about 55% more. Tensile strength is 1,400 MPa (203 ksi) vs 930 MPa (135 ksi).
Which condition does FabDigit quote by default, CWA or ST?
ST is the default Ti-13V-11Cr-3Al 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.
Which is easier to machine, Ti-13V-11Cr-3Al-CWA or Ti-13V-11Cr-3Al-ST?
Ti-13V-11Cr-3Al-ST. Its machinability rates poor (16/100) against not recommended (10/100) for Ti-13V-11Cr-3Al-CWA; for welding the order is Ti-13V-11Cr-3Al-ST first (good, 55/100) then Ti-13V-11Cr-3Al-CWA (poor, 25/100).
