1.4825 vs 1.4848 — frequently asked

Is 1.4848 stronger than 1.4825?

Yes. 1.4848 has a typical yield strength of 280 MPa (40.6 ksi) against 260 MPa (37.7 ksi) for 1.4825 — about 8% more. Tensile strength is 530 MPa (76.9 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 1.4825 or 1.4848?

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

Which is easier to machine, 1.4825 or 1.4848?

1.4825, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for 1.4848.
