Steel 1008 vs E235
Steel · grade comparison
Steel 1008 and E235 are both steel grades. E235 is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 175 MPa (25.4 ksi) for 1008, about 51% more; tensile strength follows at 420 MPa (60.9 ksi) vs 300 MPa (43.5 ksi). In exchange, 1008 is the more ductile: elongation 30% versus 27% for E235, and E235 is harder (130 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, E235 machines more easily (good vs fair).
1008Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
E235Choose it when strength drives the design, or when the part is machined in volume.
1008 vs E235: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

1008 vs E235 — frequently asked
Is E235 stronger than 1008?
Yes. E235 has a typical yield strength of 265 MPa (38.4 ksi) against 175 MPa (25.4 ksi) for 1008 — about 51% more. Tensile strength is 420 MPa (60.9 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, 1008 or E235?
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 E235?
E235. Its machinability rates good (65/100) against fair (48/100) for 1008.
