Steel DC06 vs DD11
Steel · grade comparison
Steel DC06 and DD11 are both steel grades. DD11 is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 150 MPa (21.8 ksi) for DC06, about 47% more; tensile strength follows at 380 MPa (55.1 ksi) vs 300 MPa (43.5 ksi). In exchange, DC06 is the more ductile: elongation 42% versus 32% for DD11, and DD11 is harder (110 HB vs 88 HB). DD11 runs hotter in service (350°C vs 250°C continuous) and DC06 conducts heat better (58 W/m·K vs 51 W/m·K). On the shop floor, DD11 machines more easily (good vs fair).
DC06Choose it when the part is bent, formed or impact-loaded.
DD11Choose it when strength drives the design, or when the part sees heat.
DC06 vs DD11: 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.

DC06 vs DD11 — frequently asked
Is DD11 stronger than DC06?
Yes. DD11 has a typical yield strength of 220 MPa (31.9 ksi) against 150 MPa (21.8 ksi) for DC06 — about 47% more. Tensile strength is 380 MPa (55.1 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, DC06 or DD11?
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, DC06 or DD11?
DD11. Its machinability rates good (58/100) against fair (45/100) for DC06.
