Steel 1008 vs Low Carbon Steel

Steel · grade comparison

Steel 1008 and Low Carbon Steel are both steel grades, both low carbon steel. Low Carbon Steel is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 175 MPa (25.4 ksi) for 1008, about 43% more; tensile strength follows at 400 MPa (58 ksi) vs 300 MPa (43.5 ksi). In exchange, 1008 is the more ductile: elongation 30% versus 25% for Low Carbon Steel, and Low Carbon Steel is harder (120 HB vs 86 HB). 1008 conducts heat better (60 W/m·K vs 51.9 W/m·K). On the shop floor, Low Carbon Steel machines more easily (good vs fair).

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

Low Carbon SteelChoose it when strength drives the design, or when the part is machined in volume.

1008 vs Low Carbon Steel — frequently asked

Is Low Carbon Steel stronger than 1008?

Yes. Low Carbon Steel has a typical yield strength of 250 MPa (36.3 ksi) against 175 MPa (25.4 ksi) for 1008 — about 43% more. Tensile strength is 400 MPa (58 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, 1008 or Low Carbon Steel?

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 Low Carbon Steel?

Low Carbon Steel. Its machinability rates good (62/100) against fair (48/100) for 1008.
