Home > Stainless Steel 904L Tube Fittings
Stainless Steel 904L Tube Fittings are composed of high-nickel, high-chromium stainless steel alloyed with molybdenum and copper. The typical composition includes 19–23% chromium, 23–28% nickel, 4–5% molybdenum, and 1–2% copper, providing extraordinary resistance to chlorides, acids, and harsh industrial environments. Mechanically, 904L offers excellent tensile strength, reliable yield strength, and good elongation, ensuring flexibility without compromising durability. These fittings withstand high temperatures, corrosive media, and mechanical stress, making them stable, strong, and ideal for systems requiring leak-free, long-term performance under demanding operating conditions.
