Steel 1010 vs 1023

Steel · grade comparison

Steel 1010 and 1023 are both steel grades. 1023 is the stronger of the two: yield strength 395 MPa (57.3 ksi) against 180 MPa (26.1 ksi) for 1010, about 119% more; tensile strength follows at 470 MPa (68.2 ksi) vs 325 MPa (47.1 ksi). In exchange, 1010 is the more ductile: elongation 28% versus 15% for 1023, and 1023 is harder (137 HB vs 95 HB). On the shop floor, 1023 machines more easily (good vs fair).

1010Choose it when the part is bent, formed or impact-loaded.

1023Choose it when strength drives the design, or when the part is machined in volume.

1010 vs 1023 — frequently asked

Is 1023 stronger than 1010?

Yes. 1023 has a typical yield strength of 395 MPa (57.3 ksi) against 180 MPa (26.1 ksi) for 1010 — about 119% more. Tensile strength is 470 MPa (68.2 ksi) vs 325 MPa (47.1 ksi).

Which is cheaper, 1010 or 1023?

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

Which is easier to machine, 1010 or 1023?

1023. Its machinability rates good (55/100) against fair (42/100) for 1010; for welding the order is 1010 first (excellent, 95/100) then 1023 (excellent, 90/100).
