ALUMA-TI -- A NEW HEAT RESISTANT MATERIAL FOR AUTOMOTIVE EXHAUST SYSTEM APPLICATIONS

ALUMA-TI is an aluminized product produced by hot-dip coating with a coating composition of Al + 10%Si. The base steel has been modified by adding titanium to a level such that 0.1-0.3% excess free titanium remains in solution in the substrate above that which is required to stabilize the carbon and nitrogen. This modification increases the maximum service temperature of aluminized steel from 1250 degree F to approximately 1500 degree F. The high-temperature strength of the newly developed ALUMA-TI is approximately equivalent to that of muffler grade stainless steel. Alternate exposure to high-temperature oxidation and salt fog environments indicates that ALUMA-TI has resistance to these environments at least comparable to muffler grade stainless steel.
