Titanium VT1-0-CW vs VT1-0-SR

Titanium · VT1-0 temper comparison

VT1-0-CW and VT1-0-SR are two conditions of the same titanium grade, VT1-0: CW (cold worked) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. VT1-0-CW is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 400 MPa (58 ksi) for VT1-0-SR, about 30% more; tensile strength follows at 600 MPa (87 ksi) vs 500 MPa (72.5 ksi). In exchange, VT1-0-SR is the more ductile: elongation 18% versus 10% for VT1-0-CW, and VT1-0-CW is harder (210 HB vs 180 HB). VT1-0-SR runs hotter in service (300°C vs 250°C continuous).

VT1-0-CWChoose it when strength drives the design.

VT1-0-SRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

VT1-0-CW vs VT1-0-SR — frequently asked

Is VT1-0-CW stronger than VT1-0-SR?

Yes. VT1-0-CW has a typical yield strength of 520 MPa (75.4 ksi) against 400 MPa (58 ksi) for VT1-0-SR — about 30% more. Tensile strength is 600 MPa (87 ksi) vs 500 MPa (72.5 ksi).

Which condition does FabDigit quote by default, CW or SR?

ANN is the default VT1-0 condition in the FabDigit quote flow (neither CW nor SR). 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, VT1-0-CW or VT1-0-SR?

VT1-0-CW. Its machinability rates fair (42/100) against poor (34/100) for VT1-0-SR.
