1.2344 vs 2083 — frequently asked

Is 1.2344 stronger than 2083?

Yes. 1.2344 has a typical tensile strength of 800 MPa (116 ksi) against 760 MPa (110 ksi) for 2083 — about 5% more.

Which is cheaper, 1.2344 or 2083?

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, 1.2344 or 2083?

1.2344, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for 2083; for welding the order is 1.2344 first (fair, 35/100) then 2083 (poor, 25/100).
