If you are looking for high-performance stainless steel plates for chemical equipment, we offer reliable quality 904L stainless steel plates with global delivery.
Our 904L stainless steel plates are manufactured using controlled vacuum induction melting (VIM), AOD refining, hot rolling or cold rolling, solution annealing, and pickling processes, ensuring uniform thickness, fine microstructure, and excellent surface quality. We offer various product forms, including 904L hot-rolled plates, 904L cold-rolled plates, 904L custom-sized panels, and precision-slit coils, with surface finishes including 2B, No.1, BA, or mirror polishing. The hardness is typically maintained at ≤220 HB, offering good formability, machinability, and mechanical strength.
904L stainless steel plates for chemical equipment possess excellent corrosion resistance, with a PREN value as high as 35-40, nearly 45% higher than 316L stainless steel. It exhibits superior resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking in corrosive media such as 10-20% sulfuric acid, 3-6M chloride solutions, and seawater. Compared to standard austenitic stainless steel, its service life is extended by 2-3 times, and maintenance downtime is reduced by up to 30%.
