Titanium Grade 2 vs Grade 2H

Titanium · grade comparison

Titanium Grade 2 and Grade 2H are both titanium grades. Grade 2 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 350 MPa (50.8 ksi) for Grade 2H, about 9% more. Grade 2 is the more ductile: elongation 28% versus 25% for Grade 2H, and Grade 2H is harder (160 HB vs 150 HB). On the shop floor, Grade 2H sits in a lower cost tier (high, $$$$) than Grade 2 (specialty, $$$$$).

Grade 2Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

Grade 2HChoose it when cost is the deciding factor.

Grade 2 vs Grade 2H — frequently asked

Is Grade 2 stronger than Grade 2H?

Yes. Grade 2 has a typical yield strength of 380 MPa (55.1 ksi) against 350 MPa (50.8 ksi) for Grade 2H — about 9% more. Tensile strength is 440 MPa (63.8 ksi) vs 460 MPa (66.7 ksi).

Which is cheaper, Grade 2 or Grade 2H?

Grade 2H is the lower-cost material: it sits in the high tier ($$$$) while Grade 2 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which welds better, Grade 2 or Grade 2H?

Grade 2. Its weldability rates excellent (90/100) against excellent (85/100) for Grade 2H.
