Steel 22MnB5 vs MS1700
Steel · grade comparison
Steel 22MnB5 and MS1700 are both steel grades, both high strength steel. MS1700 is the stronger of the two: yield strength 1,450 MPa (210 ksi) against 380 MPa (55.1 ksi) for 22MnB5, about 3.8 times as much; tensile strength follows at 1,780 MPa (258 ksi) vs 560 MPa (81.2 ksi). In exchange, 22MnB5 is the more ductile: elongation 22% versus 4% for MS1700, and MS1700 is harder (520 HV vs 170 HV). 22MnB5 runs hotter in service (250°C vs 200°C continuous). On the shop floor, 22MnB5 machines more easily (good vs poor) and 22MnB5 welds better (65 vs 55 out of 100).
22MnB5Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
MS1700Choose it when strength drives the design.
22MnB5 vs MS1700: 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 MS1700 — frequently asked
Is MS1700 stronger than 22MnB5?
Yes. MS1700 has a typical yield strength of 1,450 MPa (210 ksi) against 380 MPa (55.1 ksi) for 22MnB5 — about 3.8 times as much. Tensile strength is 1,780 MPa (258 ksi) vs 560 MPa (81.2 ksi).
Which is cheaper, 22MnB5 or MS1700?
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 MS1700?
22MnB5. Its machinability rates good (55/100) against poor (20/100) for MS1700; for welding the order is 22MnB5 first (good, 65/100) then MS1700 (good, 55/100).
