1.4837 vs HH — frequently asked

Is HH stronger than 1.4837?

Yes. HH has a typical yield strength of 310 MPa (45 ksi) against 265 MPa (38.4 ksi) for 1.4837 — about 17% more. Tensile strength is 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi).

Which is cheaper, 1.4837 or HH?

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 HH?

HH, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for 1.4837; for welding the order is HH first (fair, 45/100) then 1.4837 (fair, 40/100).
