Our company mainly deals with the supply and export of high quality Stainless Steel 904L Plates that are designed to perform at the highest levels in most extreme corrosive conditions. These plates are made to the standard of ASTM B625 and require the standard of UNS N08904 and belong to the family of austenitic stainless steel and have high resistance against corrosion especially in the aggressive media like sulfuric, phosphoric acid and seawater. Such plates are quite well known by their standard universal name, Alloy 904L Stainless Steel Plates.
Stainless Steel 904L is a non-stabilised low carbon austenitic stainless steel; it has very good resistance to pitting, crevice corrosion and stress corrosion cracking. Its resistance against corrosion is improved by the addition of copper against strong reducing acids. Our 904L stainless steel plates have been processed in the latest technology at Adinox Overseas so that the surface finish of the plate is uniform, dimensions are maintained and the plate is mechanically fit as well, so it is good to be used in pressure vessels and heat exchangers and condensers and other industrial applications.
Among the biggest strengths of ASTM B625 UNS N08904 plates lies their high weldability/formability. Such plates are easily weldable with normal fusion and resistance welding methods without the need to heat up after the welding. It is because of their toughness and non-magnetic behaviour under all conditions that it can be used in the chemical processing units, in oil and gas refining, marine industries, and in the pharmaceutical manufacturing units.
Adinox Overseas provides UNS N08904 stainless steel plates in different sizes depending on customer preferences with diverse thickness, width and surface finish. We maintain quality control where all of plates are in line with the international specifications such as DIN 1.4539, EN 10088 and perform under the most stressful conditions. A high nickel and molybdenum content in these plates lead to their high chloride protection and anti-intergranular corrosion.
