C14500 vs C19410 — frequently asked

Is C19410 stronger than C14500?

Yes. C19410 has a typical yield strength of 370 MPa (53.7 ksi) against 275 MPa (39.9 ksi) for C14500 — about 35% more. Tensile strength is 415 MPa (60.2 ksi) vs 310 MPa (45 ksi).

Which is cheaper, C14500 or C19410?

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 is easier to machine, C14500 or C19410?

C14500. Its machinability rates excellent (85/100) against poor (22/100) for C19410; for welding the order is C19410 first (good, 55/100) then C14500 (poor, 25/100).
