High-strength low-alloy steels and aluminum alloys have been under active study at CANMET to improve their strength and formability and to provide potential candidate material for such automotive applications as the body, frames, and exhaust systems. The development of these stronger, formable alloys is expected to contribute to the goal of producing lighter automobiles with a consequent lowering in operating costs. In support of this work it has been necessary to evaluate the corrosion characteristics of these materials, and to compare them with commonly used automotive steels.
