Thanks for the advice. I do not know much about the anodizing process myself, but an earlier internet search found the same repeated phrase that you cannot anodize 308 well b/c of its specific alloying characteristics being detrimental to the coating.
Essentially we are looking for wear...
I am currently using cast 308 aluminum and need a protective coatings similar to an anodized hard coat. What coating options exist for 308 as in nickel plating, chrome plating, etc? It should preferrably have an attractive black finish. Thanks!
