A new heat resistant aluminized steel, trade named ALUMA-TI, has been developed which has unique mechanical and corrosion properties especially attractive for high temperature applications where economy is a prime consideration for material selection. Presented are its mechanical properties and response to various corrosive environments. High temperature strength and oxidation resistance is far superior to Type I ALUMINIZED steel at temperatures above 704°C (1300°F). In combined oxidation/corrosion tests, ALUMA-TI is comparable to AISI 409 stainless steel. Therefore, ALUMA-TI is a prime material candidate for automotive exhaust systems.
