Steel 22MnB5 vs Ductibor 500
Steel · grade comparison
Steel 22MnB5 and Ductibor 500 are both steel grades. Ductibor 500 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 380 MPa (55.1 ksi) for 22MnB5, about 11% more; tensile strength follows at 620 MPa (89.9 ksi) vs 560 MPa (81.2 ksi). In exchange, 22MnB5 is the more ductile: elongation 22% versus 17% for Ductibor 500, and Ductibor 500 is harder (185 HB vs 160 HB). Ductibor 500 conducts heat better (45 W/m·K vs 32 W/m·K). On the shop floor, Ductibor 500 welds better (very good vs good) and Ductibor 500 sits in a lower cost tier (budget, $) than 22MnB5 (standard, $$).

Ductibor 500Choose it when strength drives the design, or when it will be welded.
22MnB5 vs Ductibor 500: 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.
