Steel DC05 vs SGHC
Steel · grade comparison
Steel DC05 and SGHC are both steel grades. SGHC is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 160 MPa (23.2 ksi) for DC05, about 50% more. In exchange, DC05 is the more ductile: elongation 42% versus 32% for SGHC, and SGHC is harder (95 HB vs 85 HB). DC05 runs hotter in service (300°C vs 200°C continuous). On the shop floor, DC05 welds better (excellent vs good).
DC05Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
SGHCChoose it when strength drives the design.
DC05 vs SGHC: 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 SGHC — frequently asked
Is SGHC stronger than DC05?
Yes. SGHC has a typical yield strength of 240 MPa (34.8 ksi) against 160 MPa (23.2 ksi) for DC05 — about 50% more. Tensile strength is 310 MPa (45 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, DC05 or SGHC?
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 SGHC?
SGHC, by a small margin. Both rate good for machinability — 62/100 against 55/100 for DC05; for welding the order is DC05 first (excellent, 95/100) then SGHC (good, 60/100).
