Product Description
904L steel cold drawn tube is a high alloy stainless steel tube with excellent corrosion resistance, mainly used in harsh corrosive environments.
904L stainless steel tube has better corrosion resistance to reducing acids such as sulfuric acid, phosphoric acid, and formic acid than 316L/317L, and has outstanding resistance to stress corrosion cracking (SCC) in chloride environments. The long-term use temperature is ≤400℃, and the short-term can reach 550℃.
GNEE's 904L stainless steel seamless tube can be manufactured by hot rolling or cold drawing, providing solution treatment to ensure uniform organization. And pickling, polishing or passivation to improve corrosion resistance and appearance.
