Steel DX53D vs SGCC
Steel · grade comparison
Steel DX53D and SGCC are both steel grades, both corrosion resistant steel. SGCC is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 220 MPa (31.9 ksi) for DX53D, about 14% more. SGCC is harder — 58 HRB against 50 HRB for DX53D — which matters for wear surfaces and threads. On the shop floor, DX53D forms better (excellent vs very good).
SGCCChoose it when strength drives the design, or when surface hardness matters.
DX53D vs SGCC: 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.

DX53D vs SGCC — frequently asked
Is SGCC stronger than DX53D?
Yes. SGCC has a typical yield strength of 250 MPa (36.3 ksi) against 220 MPa (31.9 ksi) for DX53D — about 14% more. Tensile strength is 330 MPa (47.9 ksi) vs 330 MPa (47.9 ksi).
Which is cheaper, DX53D or SGCC?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, DX53D or SGCC?
SGCC, by a small margin. Both rate good for machinability — 68/100 against 60/100 for DX53D.
