Steel A1011 vs DC05
Steel · grade comparison
Steel A1011 and DC05 are both steel grades. A1011 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 160 MPa (23.2 ksi) for DC05, about 56% more; tensile strength follows at 365 MPa (52.9 ksi) vs 300 MPa (43.5 ksi). In exchange, DC05 is the more ductile: elongation 42% versus 30% for A1011, and A1011 is harder (110 HB vs 85 HB). A1011 runs hotter in service (400°C vs 300°C continuous).
A1011Choose it when strength drives the design, or when the part sees heat.
DC05Choose it when the part is bent, formed or impact-loaded.
A1011 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.

A1011 vs DC05 — frequently asked
Is A1011 stronger than DC05?
Yes. A1011 has a typical yield strength of 250 MPa (36.3 ksi) against 160 MPa (23.2 ksi) for DC05 — about 56% more. Tensile strength is 365 MPa (52.9 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, A1011 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.
Which is easier to machine, A1011 or DC05?
A1011, by a small margin. Both rate good for machinability — 60/100 against 55/100 for DC05.
