Steel 1010 vs E315

Steel · grade comparison

Steel 1010 and E315 are both steel grades. E315 is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 180 MPa (26.1 ksi) for 1010, about 94% more; tensile strength follows at 520 MPa (75.4 ksi) vs 325 MPa (47.1 ksi). In exchange, 1010 is the more ductile: elongation 28% versus 24% for E315, and E315 is harder (155 HB vs 95 HB). 1010 runs hotter in service (400°C vs 350°C continuous) and 1010 conducts electricity better (12 % IACS vs 10 % IACS). On the shop floor, E315 machines more easily (good vs fair).

1010Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

E315Choose it when strength drives the design, or when the part is machined in volume.

1010 vs E315 — frequently asked

Is E315 stronger than 1010?

Yes. E315 has a typical yield strength of 350 MPa (50.8 ksi) against 180 MPa (26.1 ksi) for 1010 — about 94% more. Tensile strength is 520 MPa (75.4 ksi) vs 325 MPa (47.1 ksi).

Which is cheaper, 1010 or E315?

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, 1010 or E315?

E315. Its machinability rates good (62/100) against fair (42/100) for 1010; for welding the order is 1010 first (excellent, 95/100) then E315 (excellent, 88/100).
