C52400 vs C63000 — frequently asked

Is C52400 stronger than C63000?

Yes. C52400 has a typical yield strength of 585 MPa (84.8 ksi) against 415 MPa (60.2 ksi) for C63000 — about 41% more. Tensile strength is 690 MPa (100 ksi) vs 760 MPa (110 ksi).

Which is cheaper, C52400 or C63000?

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

Which is easier to machine, C52400 or C63000?

C63000, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for C52400; for welding the order is C63000 first (good, 65/100) then C52400 (fair, 35/100).
