Steel 1035 vs C35RC

Steel · grade comparison

Steel 1035 and C35RC are both steel grades. 1035 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for C35RC, about 7% more; tensile strength follows at 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi). In exchange, C35RC is the more ductile: elongation 25% versus 18% for 1035, and 1035 is harder (163 HB vs 150 HB).

1035Choose it when strength drives the design.

C35RCChoose it when the part is bent, formed or impact-loaded.

1035 vs C35RC — frequently asked

Is 1035 stronger than C35RC?

Yes. 1035 has a typical yield strength of 320 MPa (46.4 ksi) against 300 MPa (43.5 ksi) for C35RC — about 7% more. Tensile strength is 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 1035 or C35RC?

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 1035 over C35RC?

Pick 1035 when strength drives the design. Pick C35RC when the part is bent, formed or impact-loaded.
