When smelting sponge iron, bronze ingot is given as an output.

What should happen:
A steel ingot should be given upon smelting.

Logs (if necessary):

Additional Comments:
I was able to remedy this with crafttweaker for the time being. It appears it's pulling nuclearcraft:alloy:0 (ingotBronze) instead of nuclearcraft:alloy:5 (ingotSteel) in this case. The metadata isn't being utilized.
