Steel 1.0031 vs 1008
Steel · grade comparison
Steel 1.0031 and 1008 are both steel grades. 1.0031 is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 175 MPa (25.4 ksi) for 1008, about 9% more. 1.0031 is harder — 50 HRB against 45 HRB for 1008 — which matters for wear surfaces and threads. 1008 runs hotter in service (425°C vs 350°C continuous) and 1008 conducts heat better (60 W/m·K vs 52 W/m·K). On the shop floor, 1.0031 machines more easily (good vs fair).
1.0031Choose it when strength drives the design, or when surface hardness matters.
1008Choose it when the part sees heat.
1.0031 vs 1008: 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.

1.0031 vs 1008 — frequently asked
Is 1.0031 stronger than 1008?
Yes. 1.0031 has a typical yield strength of 190 MPa (27.6 ksi) against 175 MPa (25.4 ksi) for 1008 — about 9% more. Tensile strength is 300 MPa (43.5 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, 1.0031 or 1008?
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, 1.0031 or 1008?
1.0031. Its machinability rates good (58/100) against fair (48/100) for 1008.
