r1jakecfd 51 #1 Posted December 23, 2019 Hi guys, Just wondering if anyone has a source for hardened/abrasion resistant cutting edges for the WH 48” Plow? I know there are plenty of people selling mild steel ones out there but none seem to be hardened. The mild steel ones wear down so quickly. Thanks in advance! Merry Christmas and Happy New Year!

lynnmor 7,302 #4 Posted December 24, 2019 You could use pre-hardened 4140 or 4142 alloy steel, there are few places that offer it in 48" lengths. McMaster-Carr has AR 400 steel 6' long for $99.11 Link Share this post Link to post Share on other sites

WVHillbilly520H 10,373 #6 Posted December 24, 2019 Old car or truck leaf springs work well for this as my dad used them on his CC front blade hand made rear Brinly blade and I did on my modded 42" to 50" WH plow. Share this post Link to post Share on other sites
8ntruck 6,991 #7 Posted December 24, 2019 Depending on where you are located, there might be a steel supplier nearby. A company called ALRO comes to mind, though they are proud of their product. Might try checking with a local machine shop to see if they have any in stock or maybe could order some for you. 4140 pre-hard is pretty common and is still workable with normal tools. Gets pretty brittle if you don't use proper heating and cooling procedures when welding, though. AR series steel would be another good choice, but it is harder to work with than the 4140. Probably would need carbide drills. Good luck. Share this post Link to post Share on other sites
wallfish 16,985 #8 Posted December 24, 2019 Going 1/4 thick with the mild steel slows down the wear rate too. If you have a welder, you can run a bead along the wear edge to harden it. Depending on the wear rate you can put a new bead on every so often. Just throwing out options 1 1 Share this post Link to post Share on other sites
