I would say definitively that the piece in question is clearly not a hardened steel part for it to wear like that. The rack is hardened which makes sense for the application. After thinking about all this, if you weld, you may distort the part and since it is such a simple piece, machining one I think makes more sense. Just use a good carbon steel like 1215 and grease it well. See the link to steel properties in Mcmaster's site.
