SS 904L differs from other stainless steels by its high resistance to corrosion, especially in acidic environments. It contains added copper, making it more resistant to pitting, crevice corrosion, and stress corrosion cracking compared to standard stainless steel alloys.
SS 904L stainless steel consists of approximately 24-26% chromium, 19-23% nickel, 4-5% molybdenum, 1-2% copper, and small amounts of manganese, silicon, and carbon. The copper enhances corrosion resistance, particularly in acidic environments, while maintaining high strength.
The typical diameter range for SS 904L hollow bars varies from 10 mm to 300 mm, although custom sizes can be manufactured. These bars are available in various wall thicknesses, depending on specific application requirements and industry standards.
Stainless Steel 904L hollow bars are a go-to choice in industries that need materials with remarkable resistance to corrosion and extreme conditions. In the chemical processing sector, they are utilized for reactors, heat exchangers, and piping systems that come into contact with aggressive chemicals. In marine settings, 904L hollow bars are used in components like propellers, shafts, and offshore equipment, providing excellent resistance to seawater corrosion. The pharmaceutical, food processing, and petrochemical industries also depend on 904L hollow bars for their durability and performance in environments where resistance to chemicals, heat, and corrosion is crucial.
