Steel 22MnB5 vs Usibor 1500
Steel · grade comparison
Steel 22MnB5 and Usibor 1500 are both steel grades, both high strength steel. Usibor 1500 is the stronger of the two: yield strength 400 MPa (58 ksi) against 380 MPa (55.1 ksi) for 22MnB5, about 5% more; tensile strength follows at 600 MPa (87 ksi) vs 560 MPa (81.2 ksi). In exchange, 22MnB5 is the more ductile: elongation 22% versus 15% for Usibor 1500, and Usibor 1500 is harder (180 HB vs 160 HB). Usibor 1500 runs hotter in service (350°C vs 250°C continuous).
22MnB5Choose it when the part is bent, formed or impact-loaded.
Usibor 1500Choose it when strength drives the design, or when the part sees heat.
22MnB5 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.

22MnB5 vs Usibor 1500 — frequently asked
Is Usibor 1500 stronger than 22MnB5?
Yes. Usibor 1500 has a typical yield strength of 400 MPa (58 ksi) against 380 MPa (55.1 ksi) for 22MnB5 — about 5% more. Tensile strength is 600 MPa (87 ksi) vs 560 MPa (81.2 ksi).
Which is cheaper, 22MnB5 or Usibor 1500?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, 22MnB5 or Usibor 1500?
Usibor 1500. Its weldability rates very good (70/100) against good (65/100) for 22MnB5.
