ASTM B167 specification covers nickel-chromium-iron alloys (UNS N06600,
N06601, N06603, N06690, N06693, N06025, N06045, and N06696) and nickel-chromium-cobalt molybdenum alloy (UNS N06617) in cold-worked annealed, hot-worked annealed, and hot-finished seamless pipe and tube intended for general corrosion resistant and heat resistant applications.
UNS N06601 (Inconel 601) pipe is a combination of nickel, chromium, and iron with small amounts of other elements such as aluminum and titanium. The 2.4851 material has good high temperature resistance and can withstand temperatures up to 1200°C (2200°F), making it suitable for high temperature furnace applications.
Inconel 601 seamless pipe resists a wide range of corrosive environments, including oxidation and carburization. Alloy 601 Tube also resists thermal shock, making it ideal for heat exchangers and aerospace applications.
