Steel 1010 vs C8C

Steel · grade comparison

Steel 1010 and C8C are both steel grades. C8C is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 180 MPa (26.1 ksi) for 1010, about 114% more; tensile strength follows at 460 MPa (66.7 ksi) vs 325 MPa (47.1 ksi). In exchange, 1010 is the more ductile: elongation 28% versus 11% for C8C, and C8C is harder (135 HB vs 95 HB). 1010 runs hotter in service (400°C vs 300°C continuous).

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

C8CChoose it when strength drives the design.

1010 vs C8C — frequently asked

Is C8C stronger than 1010?

Yes. C8C has a typical yield strength of 385 MPa (55.8 ksi) against 180 MPa (26.1 ksi) for 1010 — about 114% more. Tensile strength is 460 MPa (66.7 ksi) vs 325 MPa (47.1 ksi).

Which is cheaper, 1010 or C8C?

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.

When should I choose 1010 over C8C?

Pick 1010 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C8C when strength drives the design.
