ABSTRACT:
A ferritic stainless steel containing 0.03% maximum carbon, up to about 12% manganese, about 0.03% maximum phosphorus, about 0.030% maximum sulfur, about 1.0% maximum silicon, about 12% to about 26% chromium, about 5% maximum nickel, 0.10% to 0.5% aluminum, 0.2% to 0.45% columbium, 0.03% maximum nitrogen, about 2% maximum copper, about 5% maximum molybdenum, residual titanium, and balance essentially iron. Columbium is present in excess of the amount required to react completely with carbon. The steel has high ductility and toughness in heavy sections and good corrosion resistance in weld areas.
