Grade

Why it might be chosen instead of 904L

316L

A lower cost alternative, but with much lower corrosion resistance.

6Mo

A higher resistance to pitting and crevice corrosion resistance is needed.

2205

A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.)

Super duplex

Higher corrosion resistance is needed, together with a higher strength than 904L.
