1.4567 vs 304 — frequently asked

Is 304 stronger than 1.4567?

Yes. 304 has a typical yield strength of 250 MPa (36.3 ksi) against 210 MPa (30.5 ksi) for 1.4567 — about 19% more. Tensile strength is 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 1.4567 or 304?

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

Which is easier to machine, 1.4567 or 304?

304, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for 1.4567; for welding the order is 304 first (excellent, 88/100) then 1.4567 (good, 68/100).
