Steel 1074 vs 1090

Steel · grade comparison

Steel 1074 and 1090 are both steel grades, both high carbon steel. 1090 is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 380 MPa (55.1 ksi) for 1074, about 53% more; tensile strength follows at 965 MPa (140 ksi) vs 655 MPa (95 ksi). In exchange, 1074 is the more ductile: elongation 12% versus 10% for 1090, and 1090 is harder (285 HB vs 192 HB). 1090 runs hotter in service (300°C vs 250°C continuous). On the shop floor, 1074 welds better (25 vs 15 out of 100).

1074Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

1090Choose it when strength drives the design, or when the part sees heat.

1074 vs 1090 — frequently asked

Is 1090 stronger than 1074?

Yes. 1090 has a typical yield strength of 580 MPa (84.1 ksi) against 380 MPa (55.1 ksi) for 1074 — about 53% more. Tensile strength is 965 MPa (140 ksi) vs 655 MPa (95 ksi).

Which is cheaper, 1074 or 1090?

Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which welds better, 1074 or 1090?

1074. Its weldability rates poor (25/100) against poor (15/100) for 1090.
