Titanium Grade 3 vs VT1-00

Titanium · grade comparison

Titanium Grade 3 and VT1-00 are both titanium grades. Grade 3 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 230 MPa (33.4 ksi) for VT1-00, about 83% more; tensile strength follows at 500 MPa (72.5 ksi) vs 330 MPa (47.9 ksi). In exchange, VT1-00 is the more ductile: elongation 32% versus 20% for Grade 3, and Grade 3 is harder (200 HB vs 110 HB). VT1-00 conducts heat better (20 W/m·K vs 16.4 W/m·K). On the shop floor, VT1-00 sits in a lower cost tier (high, $$$$) than Grade 3 (specialty, $$$$$).

Grade 3Choose it when strength drives the design.

VT1-00Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
