Steel 1008 vs 1022

Steel · grade comparison

Steel 1008 and 1022 are both steel grades, both low carbon steel. 1022 is the stronger of the two: yield strength 235 MPa (34.1 ksi) against 175 MPa (25.4 ksi) for 1008, about 34% more; tensile strength follows at 425 MPa (61.6 ksi) vs 300 MPa (43.5 ksi). In exchange, 1008 is the more ductile: elongation 30% versus 23% for 1022, and 1022 is harder (121 HB vs 86 HB). 1008 conducts heat better (60 W/m·K vs 51.9 W/m·K). On the shop floor, 1022 machines more easily (good vs fair).

1008Choose it when the part is bent, formed or impact-loaded.

1022Choose it when strength drives the design, or when the part is machined in volume.

1008 vs 1022 — frequently asked

Is 1022 stronger than 1008?

Yes. 1022 has a typical yield strength of 235 MPa (34.1 ksi) against 175 MPa (25.4 ksi) for 1008 — about 34% more. Tensile strength is 425 MPa (61.6 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, 1008 or 1022?

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, 1008 or 1022?

1022. Its machinability rates good (58/100) against fair (48/100) for 1008; for welding the order is 1008 first (excellent, 95/100) then 1022 (excellent, 90/100).
