Possible Alternative Grades
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.
