ASTM B161 Nickel Seamless Pipe And Tube

ASTM B161 Nickel Seamless Pipe And Tube

Alloy 200 (UNS designation N02200) and Alloy 201 (UNS designation N02201) are wrought commercially pure nickel. The alloys differ only in the maximum carbon level allowed by specification, 0.15 % maximum for Alloy 200 and 0.02 % maximum for Alloy 201. Both alloys provide highly ductile mechanical properties over a wide temperature range. Both alloys provide corrosion resistance in neutral to moderately reducing environments. In the annealed condition, either alloy possesses the approximate strength of mild steel. As-rolled material is sometimes furnished to provide higher strength levels.

ASTM B161 Nickel Seamless Pipe and Tube

ASTM B161 covers nickel (UNS N02200/Nickel 200) and low-carbon nickel (UNS N02201/Nickel 201) in the form of cold-worked seamless pipe and tube.

Alloy 200 and Alloy 201 provide high thermal and electrical conductivity in comparison to nickel base alloys, stainless steels and low alloy steels. The alloys are ferromagnetic.

Because long-time exposures of Alloy 200 in the 800 to 1200 °F (427-649 °C) range result in precipitation of a carbon phase and loss of ductility, it is not recommended for service above 600 °F (316 °C). For applications above 600 °F (316 °C), the low carbon Alloy 201 should be considered. For proposed service temperatures approaching 800 °F (427 °C), resistance to creep should be considered as a design factor.
