The facility is located near the $ 100 million Nucor Iron Carbide Inc . plant, which makes iron carbide, a coarse black powder, which like the iron briquettes, can replace a portion of scrap metal used in making steel.

Verhoeven and Pendray had already determined that the grains on the surface of the steel were grains of iron carbide their goal was to reproduce the iron carbide patterns they saw in the Damascus blades from the grains in the wootz.
