1.4837 vs ZG1Cr18Ni12Mo2Ti — frequently asked

Is 1.4837 stronger than ZG1Cr18Ni12Mo2Ti?

Yes. 1.4837 has a typical yield strength of 265 MPa (38.4 ksi) against 245 MPa (35.5 ksi) for ZG1Cr18Ni12Mo2Ti — about 8% more. Tensile strength is 520 MPa (75.4 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 1.4837 or ZG1Cr18Ni12Mo2Ti?

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, 1.4837 or ZG1Cr18Ni12Mo2Ti?

ZG1Cr18Ni12Mo2Ti, by a small margin. Both rate poor for machinability — 33/100 against 22/100 for 1.4837; for welding the order is ZG1Cr18Ni12Mo2Ti first (very good, 78/100) then 1.4837 (fair, 40/100).
