If you are looking for 904L stainless steel seamless pipes with ultra-high corrosion resistance and long service life, we can provide high-performance seamless pipes that fully comply with ASTM A312, ASTM B829, EN 10216-5, and DIN 17458 standards. These effectively address industry pain points such as pitting corrosion, stress corrosion cracking, and short service life in high-chloride, strong acid, and harsh marine environments.
SS 904L Tube Manufacturer, Check 904L Steel Cold Drawn Tube Dimensions & Sizes
Our 904L seamless pipes have outer diameters of 6-508mm and wall thicknesses of 1-50mm. They undergo pickling, passivation, and bright annealing surface treatments, with a safe operating temperature range of -196℃ to 1050℃. ASTM A312 TP 904L pipes are manufactured using cold drawing, hot rolling, and solution annealing processes. They feature a high Cr-Ni-Mo-Cu alloy composition, a PREN value greater than 34, a tensile strength ≥520MPa, and corrosion resistance far exceeding that of 316L stainless steel. They are widely used in chemical, shipbuilding, flue gas desulfurization, pharmaceutical equipment, and highly corrosive industrial piping systems.
