Steel DC05 vs DX56D
Steel · grade comparison
Steel DC05 and DX56D are both steel grades. DC05 is the stronger of the two: yield strength 160 MPa (23.2 ksi) against 150 MPa (21.8 ksi) for DX56D, about 7% more. DX56D is harder — 95 HV against 90 HV for DC05 — which matters for wear surfaces and threads. DC05 runs hotter in service (300°C vs 200°C continuous). On the shop floor, DC05 machines more easily (good vs fair).
DC05Choose it when strength drives the design, or when the part sees heat.
DX56DChoose it when surface hardness matters.
DC05 vs DX56D: 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.

DC05 vs DX56D — frequently asked
Is DC05 stronger than DX56D?
Yes. DC05 has a typical yield strength of 160 MPa (23.2 ksi) against 150 MPa (21.8 ksi) for DX56D — about 7% more. Tensile strength is 300 MPa (43.5 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, DC05 or DX56D?
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, DC05 or DX56D?
DC05. Its machinability rates good (55/100) against fair (45/100) for DX56D; for welding the order is DC05 first (excellent, 95/100) then DX56D (excellent, 88/100).
