Steel 1010 vs E220

Steel · grade comparison

Steel 1010 and E220 are both steel grades. E220 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 180 MPa (26.1 ksi) for 1010, about 39% more; tensile strength follows at 360 MPa (52.2 ksi) vs 325 MPa (47.1 ksi). In exchange, 1010 is the more ductile: elongation 28% versus 20% for E220, and E220 is harder (110 HB vs 95 HB). 1010 runs hotter in service (400°C vs 350°C continuous) and 1010 conducts electricity better (12 % IACS vs 10.5 % IACS). On the shop floor, E220 machines more easily (good vs fair).

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

E220Choose it when strength drives the design, or when the part is machined in volume.

1010 vs E220 — frequently asked

Is E220 stronger than 1010?

Yes. E220 has a typical yield strength of 250 MPa (36.3 ksi) against 180 MPa (26.1 ksi) for 1010 — about 39% more. Tensile strength is 360 MPa (52.2 ksi) vs 325 MPa (47.1 ksi).

Which is cheaper, 1010 or E220?

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 E220?

E220. Its machinability rates good (58/100) against fair (42/100) for 1010.
