I don't think so. There was one (then later, a second equal, all-class that was easier to gather materials for) tier between the i190/i195 Ironworks and the i150 set, which was i170 and was obtained through crafting with Favor materials. That stuff had to be melded well to craft the i190/i195 stuff, though not max melded (the Carbonweave set could do it, and could not be overmelded).
