C10200 vs C12200 — frequently asked

Is C12200 stronger than C10200?

Yes. C12200 has a typical yield strength of 76 MPa (11 ksi) against 69 MPa (10 ksi) for C10200 — about 10% more. Tensile strength is 235 MPa (34.1 ksi) vs 221 MPa (32.1 ksi).

Which is cheaper, C10200 or C12200?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which welds better, C10200 or C12200?

C12200. Its weldability rates excellent (85/100) against good (65/100) for C10200.
