ASTM B983 UNS N07718 Nickel Alloy Steel Tube
Overview
ASTM B983 is a standard specification established by the American Society for Testing and Materials (ASTM). It specifies the requirements for precipitation hardening nickel-based alloys in the form of seamless and welded pipe and tube.In particular, N07718 refers to a specific alloy grade called Inconel 718. Inconel 718 is a high-strength, corrosion-resistant nickel-based superalloy commonly used in various applications such as aerospace, gas turbines, and nuclear reactors.So, referring to the standard ASTM B983 N07718 would imply the specifications and requirements for seamless and welded pipes and tubes made of Inconel 718 alloy.
