Steel 22MnB5 vs CP1000
Steel · grade comparison
Steel 22MnB5 and CP1000 are both steel grades, both high strength steel. CP1000 is the stronger of the two: yield strength 800 MPa (116 ksi) against 380 MPa (55.1 ksi) for 22MnB5, about 111% more; tensile strength follows at 1,050 MPa (152 ksi) vs 560 MPa (81.2 ksi). In exchange, 22MnB5 is the more ductile: elongation 22% versus 8% for CP1000, and CP1000 is harder (315 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).
22MnB5Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
CP1000Choose it when strength drives the design.
22MnB5 vs CP1000: 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 CP1000 — frequently asked
Is CP1000 stronger than 22MnB5?
Yes. CP1000 has a typical yield strength of 800 MPa (116 ksi) against 380 MPa (55.1 ksi) for 22MnB5 — about 111% more. Tensile strength is 1,050 MPa (152 ksi) vs 560 MPa (81.2 ksi).
Which is cheaper, 22MnB5 or CP1000?
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 is easier to machine, 22MnB5 or CP1000?
22MnB5. Its machinability rates good (55/100) against poor (28/100) for CP1000.
