Stainless Steel Coil
439 stainless steel is a ferritic stainless steel with large amounts of chromium (approximately 18%) and low carbon content. This combination leads to its excellent corrosion resistance, especially in environments where chloride ions are present.
Big fire special steel, high strength steel plate, steel industry supply and demand, steel suppliers
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.
