Aluminized Steel is the preferred material for most heavy duty diesel applications.

Aluminized Steel is a low carbon steel with a thin layer of aluminum alloyed to the surface. The aluminum provides galvanic protection for the base material. Aluminized Steel parts have an ultimate service temperature of 1250 degrees F with a continuous duty temperature of 1100degreeF.

This material has excellent corrosion resistance to acidic diesel exhaust gasses. Aluminized Steel parts provide excellent field life at a reasonable cost.
