Steel 10B22 vs 41B17
Steel · grade comparison
Steel 10B22 and 41B17 are both steel grades. 10B22 is the stronger of the two: yield strength 525 MPa (76.1 ksi) against 315 MPa (45.7 ksi) for 41B17, about 67% more; tensile strength follows at 620 MPa (89.9 ksi) vs 480 MPa (69.6 ksi). In exchange, 41B17 is the more ductile: elongation 30% versus 13% for 10B22, and 10B22 is harder (180 HB vs 143 HB). 41B17 runs hotter in service (400°C vs 350°C continuous) and 10B22 conducts heat better (49 W/m·K vs 42 W/m·K). On the shop floor, 10B22 welds better (very good vs good).
10B22Choose it when strength drives the design, or when it will be welded.
41B17Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
10B22 vs 41B17: 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.

10B22 vs 41B17 — frequently asked
Is 10B22 stronger than 41B17?
Yes. 10B22 has a typical yield strength of 525 MPa (76.1 ksi) against 315 MPa (45.7 ksi) for 41B17 — about 67% more. Tensile strength is 620 MPa (89.9 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, 10B22 or 41B17?
Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 10B22 or 41B17?
41B17, by a small margin. Both rate good for machinability — 62/100 against 55/100 for 10B22; for welding the order is 10B22 first (very good, 72/100) then 41B17 (good, 60/100).
