Steel DP600 vs Usibor 1500
Steel · grade comparison
Steel DP600 and Usibor 1500 are both steel grades. Usibor 1500 is the stronger of the two: yield strength 400 MPa (58 ksi) against 380 MPa (55.1 ksi) for DP600, about 5% more. In exchange, DP600 is the more ductile: elongation 24% versus 15% for Usibor 1500, and DP600 is harder (190 HB vs 180 HB). Usibor 1500 runs hotter in service (350°C vs 200°C continuous) and DP600 conducts heat better (46 W/m·K vs 34 W/m·K). On the shop floor, Usibor 1500 machines more easily (good vs fair) and DP600 sits in a lower cost tier (budget, $) than Usibor 1500 (standard, $$).
DP600Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
Usibor 1500Choose it when strength drives the design, or when the part sees heat.
DP600 vs Usibor 1500: 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.
