Steel A1008 vs DC05
Steel · grade comparison
Steel A1008 and DC05 are both steel grades. A1008 is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 160 MPa (23.2 ksi) for DC05, about 50% more; tensile strength follows at 330 MPa (47.9 ksi) vs 300 MPa (43.5 ksi). A1008 is harder — 95 HB against 85 HB for DC05 — which matters for wear surfaces and threads. A1008 runs hotter in service (400°C vs 300°C continuous).
A1008Choose it when strength drives the design, or when surface hardness matters.
A1008 vs DC05: 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.

A1008 vs DC05 — frequently asked
Is A1008 stronger than DC05?
Yes. A1008 has a typical yield strength of 240 MPa (34.8 ksi) against 160 MPa (23.2 ksi) for DC05 — about 50% more. Tensile strength is 330 MPa (47.9 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, A1008 or DC05?
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.
When should I choose A1008 over DC05?
Pick A1008 when strength drives the design, or when surface hardness matters.
