Steel 22MnB5 vs QP1180
Steel · grade comparison
Steel 22MnB5 and QP1180 are both steel grades. QP1180 is the stronger of the two: yield strength 920 MPa (133 ksi) against 380 MPa (55.1 ksi) for 22MnB5, about 142% more; tensile strength follows at 1,240 MPa (180 ksi) vs 560 MPa (81.2 ksi). In exchange, 22MnB5 is the more ductile: elongation 22% versus 15% for QP1180, and QP1180 is harder (360 HB vs 160 HB). 22MnB5 runs hotter in service (250°C vs 200°C continuous) and 22MnB5 conducts heat better (32 W/m·K vs 28 W/m·K). On the shop floor, 22MnB5 machines more easily (good vs poor) and QP1180 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.
QP1180Choose it when strength drives the design, or when cost is the deciding factor.
22MnB5 vs QP1180: 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.
