Our aluminized steels offer formability, corrosion and heat protection as well as excellent atmospheric corrosion protection for high-temperature applications. AK Steel produces three kinds of aluminized products: Type 1, used for automotive exhaust systems, furnace heat exchangers and other heat-resistant applications; Type 1 Stainless 409 and 439, used for automotive extra long-life exhaust systems; and Type 2, used for insulation cladding, corrugated steel pipe and construction products.
Aluminized Steel is continuously hot dip coated on both sides. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating.
