Steel CP1000 vs DP1470
Steel · grade comparison
Steel CP1000 and DP1470 are both steel grades. DP1470 is the stronger of the two: yield strength 1,120 MPa (162 ksi) against 800 MPa (116 ksi) for CP1000, about 40% more; tensile strength follows at 1,520 MPa (220 ksi) vs 1,050 MPa (152 ksi). In exchange, CP1000 is the more ductile: elongation 8% versus 5.5% for DP1470, and DP1470 is harder (430 HB vs 315 HB). DP1470 conducts heat better (42 W/m·K vs 32 W/m·K). On the shop floor, CP1000 machines more easily (28 vs 18 out of 100), CP1000 welds better (good vs fair), and DP1470 sits in a lower cost tier (budget, $) than CP1000 (standard, $$).
CP1000Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
DP1470Choose it when strength drives the design, or when cost is the deciding factor.
CP1000 vs DP1470: 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.

CP1000 vs DP1470 — frequently asked
Is DP1470 stronger than CP1000?
Yes. DP1470 has a typical yield strength of 1,120 MPa (162 ksi) against 800 MPa (116 ksi) for CP1000 — about 40% more. Tensile strength is 1,520 MPa (220 ksi) vs 1,050 MPa (152 ksi).
Which is cheaper, CP1000 or DP1470?
DP1470 is the lower-cost material: it sits in the budget tier ($) while CP1000 is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, CP1000 or DP1470?
CP1000, by a small margin. Both rate poor for machinability — 28/100 against 18/100 for DP1470; for welding the order is CP1000 first (good, 65/100) then DP1470 (fair, 52/100).
