Steel 22MnB5 vs DP1180
Steel · grade comparison
Steel 22MnB5 and DP1180 are both steel grades. DP1180 is the stronger of the two: yield strength 950 MPa (138 ksi) against 380 MPa (55.1 ksi) for 22MnB5, about 150% more; tensile strength follows at 1,230 MPa (178 ksi) vs 560 MPa (81.2 ksi). In exchange, 22MnB5 is the more ductile: elongation 22% versus 7% for DP1180, and DP1180 is harder (360 HB vs 160 HB). 22MnB5 runs hotter in service (250°C vs 200°C continuous). On the shop floor, 22MnB5 machines more easily (good vs poor) and DP1180 sits in a lower cost tier (budget, $) than 22MnB5 (standard, $$).
22MnB5Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
DP1180Choose it when strength drives the design, or when cost is the deciding factor.
22MnB5 vs DP1180: 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.
