Steel 1035 vs C35E

Steel · grade comparison

Steel 1035 and C35E are both steel grades. C35E is the stronger of the two: yield strength 430 MPa (62.4 ksi) against 320 MPa (46.4 ksi) for 1035, about 34% more; tensile strength follows at 660 MPa (95.7 ksi) vs 585 MPa (84.8 ksi). C35E is the more ductile: elongation 20% versus 18% for 1035, and C35E is harder (200 HB vs 163 HB).

C35EChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

1035 vs C35E — frequently asked

Is C35E stronger than 1035?

Yes. C35E has a typical yield strength of 430 MPa (62.4 ksi) against 320 MPa (46.4 ksi) for 1035 — about 34% more. Tensile strength is 660 MPa (95.7 ksi) vs 585 MPa (84.8 ksi).

Which is cheaper, 1035 or C35E?

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, 1035 or C35E?

1035, by a small margin. Both rate good for machinability — 60/100 against 55/100 for C35E; for welding the order is 1035 first (good, 55/100) then C35E (fair, 50/100).
