ASTM B163 UNS N04400 Nickel Alloy Steel Tube
Overview
ASTM B163 N04400 is a standard specification for seamless nickel and nickel alloy condenser and heat-exchanger tubes. This specification covers tubes made from nickel-copper alloy UNS N04400, also known as Monel 400.The ASTM B163 N04400 specification covers tubes in sizes ranging from 1/8 inch to 3 inches (3.2 to 76.2 mm) in outside diameter and from 0.015 inch to 0.148 inch (0.38 to 3.76 mm) in wall thickness. The tubes are intended for use in condensers and heat exchangers for general corrosion-resisting and low or high-temperature service.
The chemical composition of the material is specified in the standard, which includes the percentage of elements such as nickel, copper, iron, manganese, carbon, silicon, and sulfur. The mechanical properties of the tubes, such as tensile strength, yield strength, and elongation, are also specified in the standard.The ASTM B163 N04400 specification also includes requirements for the manufacturing process, heat treatment, and testing of the tubes. The tests include hydrostatic or nondestructive electric tests, flaring tests, flattening tests, and hardness tests.Overall, the ASTM B163 N04400 specification provides a standard for the manufacture and testing of seamless nickel and nickel alloy condenser and heat-exchanger tubes made from UNS N04400, ensuring that the tubes meet the required chemical composition and mechanical properties for their intended use.
