ASTM B407

Incoloy 800 Seamless Pipe and Tube

ASTM B407 Standards And Specifications

ASTM B407 specification covers UNS N08800 in the form of cold-worked and hot-finished annealed seamless pipe and tube. This Specification is basically used for Incoloy 800 Seamless Pipe and Tube.

ASTM B407 - Seamless Pipe and Tube

Astm B407 Seamless Pipe Tube

ASTM B407 Seamless Pipeis composed of Nickel-Iron-Chromium Alloys. This series of alloys has also found extensive use in the high-temperature petrochemical environments, where sulfur-containing feedstocks (naphtha and heavy oils) are cracked into component distillate parts. Not only were they resistant to chloride-ion stress-corrosion cracking, but they also offered resistance to polythionic acid cracking. Nickel is a versatile element and will alloy with most metals. Wide solubility ranges between iron, chromium, and nickel make possible many alloy combinations.

Scope And Manufacturing

ASTM B407 specification covers Inoloy 800 in the form of cold-worked and hot-finished annealed seamless pipe and tube. UNS N08800 Alloys are normally employed in service temperatures up to and including 1100°F (593°C) The materials shall be heat treated at certain annealing temperatures and shall conform to the chemical composition limits for nickel, chromium, iron, manganese, carbon, copper, silicon, sulfur, aluminum, titanium, columbium, molybdenum, niobium, tantalum, phosphorus, tungsten, cobalt, nitrogen, and boron. Planimetric method of measurement and tension test shall be conducted in full tubular size, longitudinal strip, or round specimens in the direction of fabrication to determine the grain size and mechanical properties, respectively. These materials shall conform to the specified grain size, yield strength, tensile strength, and elongation requirements. Each pipe or tube shall be subjected to hydrostatic or nondestructive eddy-current tests to determine the allowable fiber stress and to detect significant discontinuities such as drilled hole and transverse tangential notch. The cold-drawn material shall be commercially straight, uniform in quality and temper, smooth, and free of bends, kinks, and other injurious imperfections.
