Steel 1090 vs T10

Steel · grade comparison

Steel 1090 and T10 are both steel grades. 1090 is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 420 MPa (60.9 ksi) for T10, about 38% more; tensile strength follows at 965 MPa (140 ksi) vs 720 MPa (104 ksi). In exchange, T10 is the more ductile: elongation 18% versus 10% for 1090, and 1090 is harder (285 HB vs 192 HB). On the shop floor, T10 machines more easily (48 vs 38 out of 100) and 1090 sits in a lower cost tier (standard, $$) than T10 (premium, $$$).

1090Choose it when strength drives the design, or when cost is the deciding factor.

T10Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

1090 vs T10 — frequently asked

Is 1090 stronger than T10?

Yes. 1090 has a typical yield strength of 580 MPa (84.1 ksi) against 420 MPa (60.9 ksi) for T10 — about 38% more. Tensile strength is 965 MPa (140 ksi) vs 720 MPa (104 ksi).

Which is cheaper, 1090 or T10?

1090 is the lower-cost material: it sits in the standard tier ($$) while T10 is premium ($$$). 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, 1090 or T10?

T10, by a small margin. Both rate fair for machinability — 48/100 against 38/100 for 1090.
