1141 vs 1330 — frequently asked

Is 1330 stronger than 1141?

Yes. 1330 has a typical yield strength of 415 MPa (60.2 ksi) against 360 MPa (52.2 ksi) for 1141 — about 15% more. Tensile strength is 690 MPa (100 ksi) vs 675 MPa (97.9 ksi).

Which is cheaper, 1141 or 1330?

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, 1141 or 1330?

1141, by a small margin. Both rate good for machinability — 68/100 against 58/100 for 1330; for welding the order is 1330 first (fair, 45/100) then 1141 (poor, 25/100).
