Steel 1035 vs E470

Steel · grade comparison

Steel 1035 and E470 are both steel grades. E470 is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 320 MPa (46.4 ksi) for 1035, about 81% more; tensile strength follows at 700 MPa (102 ksi) vs 585 MPa (84.8 ksi). In exchange, 1035 is the more ductile: elongation 18% versus 10% for E470, and E470 is harder (210 HB vs 163 HB). 1035 runs hotter in service (425°C vs 300°C continuous) and 1035 conducts electricity better (10.8 % IACS vs 9.6 % IACS). On the shop floor, 1035 welds better (good vs poor).

1035Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

E470Choose it when strength drives the design.

1035 vs E470 — frequently asked

Is E470 stronger than 1035?

Yes. E470 has a typical yield strength of 580 MPa (84.1 ksi) against 320 MPa (46.4 ksi) for 1035 — about 81% more. Tensile strength is 700 MPa (102 ksi) vs 585 MPa (84.8 ksi).

Which is cheaper, 1035 or E470?

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 E470?

1035, by a small margin. Both rate good for machinability — 60/100 against 55/100 for E470; for welding the order is 1035 first (good, 55/100) then E470 (poor, 32/100).
