I will need to replace the 'cutting' edge on my road drag again soon and would like something longer lasting than the 3/16 mild steel I'vebeen using. I will use 1/4 on the next one, but would like to try a higher carbon content steel. Machinery handbook lists 1070 or 1080 for plow shares. Would this be able to be welded to mild steel using lincoln inner shield? And would it require hardening to be more abrasion resistant? Or is there some other metal that would work well?
