Titanium Grade 2H vs Grade 3

Titanium · grade comparison

Titanium Grade 2H and Grade 3 are both titanium grades. Grade 3 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 350 MPa (50.8 ksi) for Grade 2H, about 20% more; tensile strength follows at 500 MPa (72.5 ksi) vs 460 MPa (66.7 ksi). In exchange, Grade 2H is the more ductile: elongation 25% versus 20% for Grade 3, and Grade 3 is harder (200 HB vs 160 HB). On the shop floor, Grade 2H sits in a lower cost tier (high, $$$$) than Grade 3 (specialty, $$$$$).

Grade 2HChoose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.

Grade 3Choose it when strength drives the design.

Grade 2H vs Grade 3 — frequently asked

Is Grade 3 stronger than Grade 2H?

Yes. Grade 3 has a typical yield strength of 420 MPa (60.9 ksi) against 350 MPa (50.8 ksi) for Grade 2H — about 20% more. Tensile strength is 500 MPa (72.5 ksi) vs 460 MPa (66.7 ksi).

Which is cheaper, Grade 2H or Grade 3?

Grade 2H is the lower-cost material: it sits in the high tier ($$$$) while Grade 3 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, Grade 2H or Grade 3?

Grade 2H, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for Grade 3.
