ASTM B167 UNS N06600 Seamless Pipe Manufacturer
ASTM B167 covers seamless pipes and tubes manufactured from Nickel-Chromium-Iron alloy (Inconel 600, UNS N06600). These pipes and tubes are widely used in high-temperature and corrosion-resistant applications due to their exceptional metallurgical stability and mechanical strength.
What Is ASTM B167?
ASTM B167 is the standard specification for Nickel-Chromium-Iron alloy (UNS N06600) seamless pipes and tubes intended for high-temperature or corrosive environment
It is th Standard Specification for Nickel-Chromium-Iron Alloys (UNS N06600, N06601, N06603, N06690, N06693, N06025, N06045, and N06696), Nickel-Chromium-Cobalt-Molybdenum Alloy (UNS N06617), and Nickel-Iron-Chromium-Tungsten Alloy (UNS N06674) Seamless Pipe and Tube
