Ferritic stainless 439
Grade 439 is a ferritic stainless steel that outperforms type 409 in both Oxidation resistance and corrrosion resistance.
Type 439 stainless is stabilized with a titanium addition resulting in good weldability. It has higher thermal conductivity and lower coefficient of expansion than austensitic grade 304.
