Titanium Grade 1 vs Grade 2H

Titanium · grade comparison

Titanium Grade 1 and Grade 2H are both titanium grades. Grade 2H is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 220 MPa (31.9 ksi) for Grade 1, about 59% more; tensile strength follows at 460 MPa (66.7 ksi) vs 300 MPa (43.5 ksi). In exchange, Grade 1 is the more ductile: elongation 30% versus 25% for Grade 2H, and Grade 2H is harder (160 HB vs 120 HB). Grade 1 conducts heat better (20 W/m·K vs 16.4 W/m·K). On the shop floor, Grade 2H sits in a lower cost tier (high, $$$$) than Grade 1 (specialty, $$$$$).

Grade 1Choose it when the part is bent, formed or impact-loaded.

Grade 2HChoose it when strength drives the design, or when cost is the deciding factor.

Grade 1 vs Grade 2H — frequently asked

Is Grade 2H stronger than Grade 1?

Yes. Grade 2H has a typical yield strength of 350 MPa (50.8 ksi) against 220 MPa (31.9 ksi) for Grade 1 — about 59% more. Tensile strength is 460 MPa (66.7 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, Grade 1 or Grade 2H?

Grade 2H is the lower-cost material: it sits in the high tier ($$$$) while Grade 1 is specialty ($$$$$). 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 1 or Grade 2H?

Grade 1. Its weldability rates excellent (90/100) against excellent (85/100) for Grade 2H.
