Steel 1035 vs C56E2

Steel · grade comparison

Steel 1035 and C56E2 are both steel grades. C56E2 is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 320 MPa (46.4 ksi) for 1035, about 9% more; tensile strength follows at 620 MPa (89.9 ksi) vs 585 MPa (84.8 ksi). C56E2 is harder — 180 HB against 163 HB for 1035 — which matters for wear surfaces and threads. 1035 runs hotter in service (425°C vs 300°C continuous) and 1035 conducts electricity better (10.8 % IACS vs 9.5 % IACS). On the shop floor, 1035 machines more easily (good vs fair) and 1035 welds better (good vs poor).

1035Choose it when the part sees heat, or when the part is machined in volume.

C56E2Choose it when strength drives the design, or when surface hardness matters.

1035 vs C56E2 — frequently asked

Is C56E2 stronger than 1035?

Yes. C56E2 has a typical yield strength of 350 MPa (50.8 ksi) against 320 MPa (46.4 ksi) for 1035 — about 9% more. Tensile strength is 620 MPa (89.9 ksi) vs 585 MPa (84.8 ksi).

Which is cheaper, 1035 or C56E2?

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 C56E2?

1035. Its machinability rates good (60/100) against fair (45/100) for C56E2; for welding the order is 1035 first (good, 55/100) then C56E2 (poor, 25/100).
