904L stainless steel balls are high-alloy austenitic stainless steel balls designed for highly corrosive environments. With high nickel, molybdenum and copper content, they provide excellent resistance to acids, chlorides and pitting corrosion.
Also known as super austenitic stainless steel balls, 904L balls are used in highly corrosive chemical and marine-related environments.
904L stainless steel balls are manufactured from high-alloy austenitic stainless steel with elevated nickel, molybdenum and copper content.
Compared with standard stainless steels such as 304 or 316, 904L offers significantly improved resistance to acids, chlorides and pitting corrosion, making it suitable for severe corrosion-sensitive industrial environments.
