1.4710 vs 1.4729 — frequently asked

Is 1.4729 stronger than 1.4710?

Yes. 1.4729 has a typical yield strength of 420 MPa (60.9 ksi) against 290 MPa (42.1 ksi) for 1.4710 — about 45% more. Tensile strength is 680 MPa (98.6 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 1.4710 or 1.4729?

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, 1.4710 or 1.4729?

1.4710, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for 1.4729; for welding the order is 1.4710 first (poor, 30/100) then 1.4729 (poor, 25/100).
