Aluminized Type 2 steel was developed for superior environmental corrosion resistance and combines the strength of a steel substrate with the corrosion resistance of aluminum. It is produced by continuous hot dip coating of steel strip in a bath of molten, commercially pure aluminum. Cleaning the strip in a non-oxidizing/reducing furnace atmosphere assures a pristine surface for coating adherence. Interaction of molten aluminum with the steel surface produces a metallurgical bond and provides corrosion protection. Line speed, bath temperature and air finishing knives control aluminum coating thickness.
