ASTM B166

This specification covers nickel-chromium-iron alloys (UNS N06600, N06601, N06603, N06690, N06693, N06025, and N06045)* and nickel-chromium-cobalt-molybdenum alloy (UNS N06617) in the form of hot-finished and cold-worked rounds, squares, hexagons, rectangles, and cold-worked wire. The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
