C33000 vs C48200 — frequently asked

Is C48200 stronger than C33000?

Yes. C48200 has a typical yield strength of 172 MPa (24.9 ksi) against 110 MPa (16 ksi) for C33000 — about 56% more. Tensile strength is 379 MPa (55 ksi) vs 340 MPa (49.3 ksi).

Which is cheaper, C33000 or C48200?

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.

When should I choose C33000 over C48200?

Pick C33000 when the part is bent, formed or impact-loaded. Pick C48200 when strength drives the design.
