Steel 1030 vs E470

Steel · grade comparison

Steel 1030 and E470 are both steel grades. E470 is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 260 MPa (37.7 ksi) for 1030, about 123% more; tensile strength follows at 700 MPa (102 ksi) vs 470 MPa (68.2 ksi). In exchange, 1030 is the more ductile: elongation 20% versus 10% for E470, and E470 is harder (210 HB vs 137 HB). 1030 runs hotter in service (400°C vs 300°C continuous). On the shop floor, 1030 welds better (good vs poor).

1030Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

E470Choose it when strength drives the design.

1030 vs E470 — frequently asked

Is E470 stronger than 1030?

Yes. E470 has a typical yield strength of 580 MPa (84.1 ksi) against 260 MPa (37.7 ksi) for 1030 — about 123% more. Tensile strength is 700 MPa (102 ksi) vs 470 MPa (68.2 ksi).

Which is cheaper, 1030 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 welds better, 1030 or E470?

1030. Its weldability rates good (62/100) against poor (32/100) for E470.
