Steel DC05 vs DD13
Steel · grade comparison
Steel DC05 and DD13 are both steel grades. DD13 is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 160 MPa (23.2 ksi) for DC05, about 44% more; tensile strength follows at 340 MPa (49.3 ksi) vs 300 MPa (43.5 ksi). In exchange, DC05 is the more ductile: elongation 42% versus 36% for DD13, and DD13 is harder (105 HB vs 85 HB). DD13 runs hotter in service (350°C vs 300°C continuous).
DC05Choose it when the part is bent, formed or impact-loaded.
DD13Choose it when strength drives the design, or when the part sees heat.
DC05 vs DD13: 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 DD13 — frequently asked
Is DD13 stronger than DC05?
Yes. DD13 has a typical yield strength of 230 MPa (33.4 ksi) against 160 MPa (23.2 ksi) for DC05 — about 44% more. Tensile strength is 340 MPa (49.3 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, DC05 or DD13?
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.
When should I choose DC05 over DD13?
Pick DC05 when the part is bent, formed or impact-loaded. Pick DD13 when strength drives the design, or when the part sees heat.
