1.4849 vs HN — frequently asked

What is the difference between 1.4849 and HN?

Stainless Steel 1.4849 and HN are both stainless steel grades. Both yield at about 250 MPa — strength does not separate them. HN is stiffer (180 GPa vs 170 GPa).

Which is cheaper, 1.4849 or HN?

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

Which is easier to machine, 1.4849 or HN?

HN, by a small margin. Both rate poor for machinability — 28/100 against 20/100 for 1.4849; for welding the order is 1.4849 first (good, 55/100) then HN (fair, 40/100).
