ASTM B677 TP904L nickel alloy seamless corrosion resistant pipe
ASTM B677 TP904L nickel alloy seamless corrosion resistant pipe
ASTM B677 TP904L nickel alloy seamless pipe is a high-performance material made from high-alloy stainless steel, renowned for its exceptional corrosion resistance in a wide range of environments, including sulfuric, acetic, and phosphoric acids. Key features include seamless construction, high strength, and excellent pressure resistance; low carbon content for excellent weldability and no sensitization; and the addition of molybdenum and copper for enhanced resistance to pitting, crevice, and general corrosion. It is widely used in industries such as the chemical, oil and gas, desalination, and power generation.
What are the specifications for 904L pipe?
UNS N08904 pipe has a density of 7.95 g/cm³, meeting international and national standards. These pipes have a melting point as high as 1350°C. 904L pipe is widely used where the corrosion resistance of 316L and 317L pipes is insufficient.
