Steel 1008 vs E275

Steel · grade comparison

Steel 1008 and E275 are both steel grades. E275 is the stronger of the two: yield strength 310 MPa (45 ksi) against 175 MPa (25.4 ksi) for 1008, about 77% more; tensile strength follows at 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi). In exchange, 1008 is the more ductile: elongation 30% versus 26% for E275, and E275 is harder (140 HB vs 86 HB). 1008 runs hotter in service (425°C vs 350°C continuous) and 1008 conducts heat better (60 W/m·K vs 50 W/m·K). On the shop floor, E275 machines more easily (good vs fair).

1008Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

E275Choose it when strength drives the design, or when the part is machined in volume.

1008 vs E275 — frequently asked

Is E275 stronger than 1008?

Yes. E275 has a typical yield strength of 310 MPa (45 ksi) against 175 MPa (25.4 ksi) for 1008 — about 77% more. Tensile strength is 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, 1008 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, 1008 or E275?

E275. Its machinability rates good (62/100) against fair (48/100) for 1008; for welding the order is 1008 first (excellent, 95/100) then E275 (excellent, 90/100).
