Steel 1008 vs C22E

Steel · grade comparison

Steel 1008 and C22E are both steel grades. C22E is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 175 MPa (25.4 ksi) for 1008, about 66% more; tensile strength follows at 500 MPa (72.5 ksi) vs 300 MPa (43.5 ksi). In exchange, 1008 is the more ductile: elongation 30% versus 26% for C22E, and C22E is harder (140 HB vs 86 HB). 1008 conducts heat better (60 W/m·K vs 51 W/m·K). On the shop floor, C22E machines more easily (very good vs fair).

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

C22EChoose it when strength drives the design, or when the part is machined in volume.

1008 vs C22E — frequently asked

Is C22E stronger than 1008?

Yes. C22E has a typical yield strength of 290 MPa (42.1 ksi) against 175 MPa (25.4 ksi) for 1008 — about 66% more. Tensile strength is 500 MPa (72.5 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, 1008 or C22E?

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 C22E?

C22E. Its machinability rates very good (70/100) against fair (48/100) for 1008.
