439 Stainless Steel Plate

439 steel is in the ordinary ferrite material (430) on the basis of reducing the content of C, while adding Ti and other stabilizing elements, so that the steel intergranular corrosion resistance, formability and weldability are improved. Compared with the 304 steel, although the elongation is low (about 30%), but the strength, corrosion resistance, and corrosion resistance is better than 200 series materials.
