Steel DC05 vs DC06
Steel · grade comparison
Steel DC05 and DC06 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 DC06, about 7% more. DC05 runs hotter in service (300°C vs 250°C continuous) and DC06 conducts electricity better (13 % IACS vs 11.5 % IACS). On the shop floor, DC05 machines more easily (good vs fair).
DC05Choose it when strength drives the design, or when the part sees heat.
DC05 vs DC06: 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 DC06 — frequently asked
Is DC05 stronger than DC06?
Yes. DC05 has a typical yield strength of 160 MPa (23.2 ksi) against 150 MPa (21.8 ksi) for DC06 — about 7% more. Tensile strength is 300 MPa (43.5 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, DC05 or DC06?
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 DC06?
DC05. Its machinability rates good (55/100) against fair (45/100) for DC06.
