904L stainless steel, also known as Alloy 904L, is a high-alloy stainless steel that excels in corrosion resistance, especially in environments with strong acids, strong alkalis, and high chloride content. It demonstrates remarkable resistance to corrosive media such as sulfuric acid, hydrochloric acid, phosphoric acid, and nitric acid.
904L stainless steel finds applications in various industries, including chemical processing, marine engineering, oil and gas production, food processing, and medical equipment manufacturing. In chemical processing, it is used to fabricate reactors, storage tanks, pipelines, and valves due to its exceptional resistance to acids and alkalis. In marine engineering, its resistance to seawater corrosion makes it suitable for the construction of offshore platforms, oil drilling equipment, and seawater desalination facilities.
