Nickel Alloy Tube Specification – ASTM B167


This specification discusses 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. The material shall conform to the required chemical composition for nickel, chromium, iron, manganese, molybdenum, cobalt, aluminum, carbon, copper, boron, silicon, sulfur, titanium, niobium, phosphorous, zirconium, yttrium, and cerium. Three tests are required: chemical analysis, tension test, and hydrostatic or nondestructive electric test. The material must have the required mechanical properties: tensile strength, yield strength, elongation, nondestructive electric test, and rounding method.
