1132 vs 1215 — frequently asked

Is 1132 stronger than 1215?

Yes. 1132 has a typical yield strength of 530 MPa (76.9 ksi) against 250 MPa (36.3 ksi) for 1215 — about 112% more. Tensile strength is 620 MPa (89.9 ksi) vs 415 MPa (60.2 ksi).

Which is cheaper, 1132 or 1215?

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

Which is easier to machine, 1132 or 1215?

1215. Its machinability rates excellent (85/100) against very good (78/100) for 1132; for welding the order is 1132 first (poor, 25/100) then 1215 (poor, 20/100).
