Aluminized Steel Type 1 Stainless 409 and 439

Aluminized 409 and 439 Stainless Steel products have been developed to provide the automotive industry with life-of-the-car exhaust system materials. The Type 1 hot dip aluminum coating provides excellent resistance to pitting from muffler condensate and road salt, allowing the exhaust system to resist internal chlorides and retain good external appearance, even at uncoated welds. The aluminum coating significantly extends the life of the exhaust system over that of bare stainless. The coating is Type 1 Aluminized containing approximately 91% aluminum and 9% silicon.
