Steel DP450 vs Usibor 1500
Steel · grade comparison
Steel DP450 and Usibor 1500 are both steel grades. Usibor 1500 is the stronger of the two: yield strength 400 MPa (58 ksi) against 300 MPa (43.5 ksi) for DP450, about 33% more; tensile strength follows at 600 MPa (87 ksi) vs 500 MPa (72.5 ksi). In exchange, DP450 is the more ductile: elongation 29% versus 15% for Usibor 1500, and Usibor 1500 is harder (180 HB vs 143 HB). Usibor 1500 runs hotter in service (350°C vs 200°C continuous) and DP450 conducts heat better (48 W/m·K vs 34 W/m·K). On the shop floor, DP450 welds better (82 vs 70 out of 100) and DP450 sits in a lower cost tier (budget, $) than Usibor 1500 (standard, $$).
DP450Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
Usibor 1500Choose it when strength drives the design, or when the part sees heat.
DP450 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.
