Steel 10B22 vs 15B41

Steel · grade comparison

Steel 10B22 and 15B41 are both steel grades. 15B41 is the stronger of the two: yield strength 1,030 MPa (149 ksi) against 525 MPa (76.1 ksi) for 10B22, about 96% more; tensile strength follows at 1,160 MPa (168 ksi) vs 620 MPa (89.9 ksi). 15B41 is harder — 336 HB against 180 HB for 10B22 — which matters for wear surfaces and threads. 10B22 runs hotter in service (350°C vs 300°C continuous) and 10B22 conducts heat better (49 W/m·K vs 44 W/m·K). On the shop floor, 10B22 machines more easily (good vs fair), 10B22 welds better (very good vs poor), and 10B22 forms better (excellent vs poor).

10B22Choose it when the part sees heat, or when the part is machined in volume.

15B41Choose it when strength drives the design, or when surface hardness matters.

10B22 vs 15B41 — frequently asked

Is 15B41 stronger than 10B22?

Yes. 15B41 has a typical yield strength of 1,030 MPa (149 ksi) against 525 MPa (76.1 ksi) for 10B22 — about 96% more. Tensile strength is 1,160 MPa (168 ksi) vs 620 MPa (89.9 ksi).

Which is cheaper, 10B22 or 15B41?

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 15B41?

10B22. Its machinability rates good (55/100) against fair (40/100) for 15B41; for welding the order is 10B22 first (very good, 72/100) then 15B41 (poor, 25/100).
