C17300 vs C17510 — frequently asked

Is C17300 stronger than C17510?

Yes. C17300 has a typical yield strength of 220 MPa (31.9 ksi) against 170 MPa (24.7 ksi) for C17510 — about 29% more. Tensile strength is 470 MPa (68.2 ksi) vs 310 MPa (45 ksi).

Which is cheaper, C17300 or C17510?

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, C17300 or C17510?

C17300. Its machinability rates fair (50/100) against poor (25/100) for C17510; for welding the order is C17510 first (good, 58/100) then C17300 (poor, 15/100).
