Type 439 is a ferritic stainless steel that is best suited for use in oxidizing environments, where excellent corrosion resistance is needed. 439 Is often used in place of Type 409 where higher thermal conductivity is required. When application temperatures are too high for type 409 , type 439 provides good oxidation and corrosion resistance for many automotive exhaust system components and residential furnance primary heat exchangers Type 439 also has superior formability capabilities and is heavily used in the automotive industry. Stainless steel grade 439 is capable of being made into complex shapes such as tubular manifolds and exhaust system components, where temperatures tend to go beyond the oxidation limit of grade 409 steel. 439 is also preferred where wet corrosion resistance especially to chlorides is needed Stainless steel grade 439 has good weldability, brightness, and pitting corrosion resistance. It polishes well, and is good for deep drawing Stainless steel grade 439 is applied in areas that require oxidation and corrosion resistance. It is also widely used in catering equipment.Stainless steel 439 flat rolled stainless steel is magnetic in all conditions. Stainless steel 439 has outstanding forming abilities even for difficult and unusual shapes.Stainless steel 439 Good general corrosion resistance, especially in fresh waters and mildly oxidizing environment Stainless steel 439 replace Stainless steel 304 in oxidizing environment condition
