Steel A1008 vs DC03
Steel · grade comparison
Steel A1008 and DC03 are both steel grades. A1008 is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 195 MPa (28.3 ksi) for DC03, about 23% more; tensile strength follows at 330 MPa (47.9 ksi) vs 310 MPa (45 ksi). DC03 is harder — 55 HRB against 50 HRB for A1008 — which matters for wear surfaces and threads. A1008 runs hotter in service (400°C vs 350°C continuous).
A1008Choose it when strength drives the design, or when the part sees heat.
DC03Choose it when surface hardness matters.
A1008 vs DC03: 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 DC03 — frequently asked
Is A1008 stronger than DC03?
Yes. A1008 has a typical yield strength of 240 MPa (34.8 ksi) against 195 MPa (28.3 ksi) for DC03 — about 23% more. Tensile strength is 330 MPa (47.9 ksi) vs 310 MPa (45 ksi).
Which is cheaper, A1008 or DC03?
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, A1008 or DC03?
A1008. Its machinability rates good (55/100) against fair (50/100) for DC03.
