Steel DP1180 vs Usibor 1500
Steel · grade comparison
Steel DP1180 and Usibor 1500 are both steel grades. DP1180 is the stronger of the two: yield strength 950 MPa (138 ksi) against 400 MPa (58 ksi) for Usibor 1500, about 138% more; tensile strength follows at 1,230 MPa (178 ksi) vs 600 MPa (87 ksi). In exchange, Usibor 1500 is the more ductile: elongation 15% versus 7% for DP1180, and DP1180 is harder (360 HB vs 180 HB). Usibor 1500 runs hotter in service (350°C vs 200°C continuous). On the shop floor, Usibor 1500 machines more easily (good vs poor) and DP1180 sits in a lower cost tier (budget, $) than Usibor 1500 (standard, $$).
DP1180Choose it when strength drives the design, or when cost is the deciding factor.
Usibor 1500Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
DP1180 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.
