Steel 1008 vs 1020
Steel · grade comparison
Steel 1008 and 1020 are both steel grades, both low carbon steel. 1020 is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 175 MPa (25.4 ksi) for 1008, about 100% 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 15% for 1020, and 1020 is harder (121 HB vs 86 HB). 1008 conducts heat better (60 W/m·K vs 51.9 W/m·K).
1008Choose it when the part is bent, formed or impact-loaded.
1020Choose it when strength drives the design.
1008 vs 1020: 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 1020 — frequently asked
Is 1020 stronger than 1008?
Yes. 1020 has a typical yield strength of 350 MPa (50.8 ksi) against 175 MPa (25.4 ksi) for 1008 — about 100% more. Tensile strength is 420 MPa (60.9 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, 1008 or 1020?
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 1020?
1020. Its machinability rates good (57/100) against fair (48/100) for 1008.
