Steel 10B22 vs 20CrMnTiB

Steel · grade comparison

Steel 10B22 and 20CrMnTiB are both steel grades. 10B22 is the stronger of the two: yield strength 525 MPa (76.1 ksi) against 400 MPa (58 ksi) for 20CrMnTiB, about 31% more. In exchange, 20CrMnTiB is the more ductile: elongation 22% versus 13% for 10B22. 10B22 runs hotter in service (350°C vs 200°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 fair).

10B22Choose it when strength drives the design, or when the part sees heat.

20CrMnTiBChoose it when the part is bent, formed or impact-loaded.

10B22 vs 20CrMnTiB — frequently asked

Is 10B22 stronger than 20CrMnTiB?

Yes. 10B22 has a typical yield strength of 525 MPa (76.1 ksi) against 400 MPa (58 ksi) for 20CrMnTiB — about 31% more. Tensile strength is 620 MPa (89.9 ksi) vs 620 MPa (89.9 ksi).

Which is cheaper, 10B22 or 20CrMnTiB?

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 welds better, 10B22 or 20CrMnTiB?

10B22. Its weldability rates very good (72/100) against fair (35/100) for 20CrMnTiB.
