Steel DC05 vs DD11

Steel · grade comparison

Steel DC05 and DD11 are both steel grades. DD11 is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 160 MPa (23.2 ksi) for DC05, about 38% more; tensile strength follows at 380 MPa (55.1 ksi) vs 300 MPa (43.5 ksi). In exchange, DC05 is the more ductile: elongation 42% versus 32% for DD11, and DD11 is harder (110 HB vs 85 HB). DD11 runs hotter in service (350°C vs 300°C continuous).

DC05Choose it when the part is bent, formed or impact-loaded.

DD11Choose it when strength drives the design, or when the part sees heat.

DC05 vs DD11 — frequently asked

Is DD11 stronger than DC05?

Yes. DD11 has a typical yield strength of 220 MPa (31.9 ksi) against 160 MPa (23.2 ksi) for DC05 — about 38% more. Tensile strength is 380 MPa (55.1 ksi) vs 300 MPa (43.5 ksi).

Which is cheaper, DC05 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.

When should I choose DC05 over DD11?

Pick DC05 when the part is bent, formed or impact-loaded. Pick DD11 when strength drives the design, or when the part sees heat.
