434 Stainless Steel Plate
Alloy stainless steel 434 is one of the most widely used of the ferritic stainless steels. The addition of molybdenum improves the alloy’s general corrosion resistance and makes the alloy resistant to attack by deicing chemicals. It combines good heat and oxidation resistance up to 1500oF (816oC) as well as good mechanical properties.
