The weld on bucket cutting edge is made from hardened 1055 Carbon steel to maximize the performance and reduce wear. The bar comes unpainted so you can weld it immediately.
“Straight forward, hardened carbon steel. I was able to weld the new edge to the original bucket, with a Hobart Mig Welder, wire feed/gas shielded. Used .035” Hobart ER70S-6 Solid Wire, Carbon Steel. Took 1 1/2 (2lb) Spools. A Stick Welder may be a little easier, with the thickness of the edge, but a Mig will work if you take your time.”
