I doubt they need it, the most vital guess for me would be that OP don't know the metal itself.
Note: you should get the item discovered by current char, i.e getting it directly from smelter (or (re)smelting the bar from nuggets, though you still need to discover any metal bar in order to unlcok those recipes, which in case you know any metal bar would unlock you Stonestead at least)
