Steel 1010 vs E275

Steel · grade comparison

Steel 1010 and E275 are both steel grades. E275 is the stronger of the two: yield strength 310 MPa (45 ksi) against 180 MPa (26.1 ksi) for 1010, about 72% more; tensile strength follows at 480 MPa (69.6 ksi) vs 325 MPa (47.1 ksi). E275 is harder — 140 HB against 95 HB for 1010 — which matters for wear surfaces and threads. 1010 runs hotter in service (400°C vs 350°C continuous). On the shop floor, E275 machines more easily (good vs fair) and 1010 forms better (excellent vs very good).

1010 vs E275 — frequently asked

Is E275 stronger than 1010?

Yes. E275 has a typical yield strength of 310 MPa (45 ksi) against 180 MPa (26.1 ksi) for 1010 — about 72% more. Tensile strength is 480 MPa (69.6 ksi) vs 325 MPa (47.1 ksi).

Which is cheaper, 1010 or E275?

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 E275?

E275. Its machinability rates good (62/100) against fair (42/100) for 1010; for welding the order is 1010 first (excellent, 95/100) then E275 (excellent, 90/100).
