Nickel Alloy Tube Specification – ASTM B674

Overview:

This specification covers the standard for UNS N08923, UNS N0835, and UNS N08926 welded tube for general corrosion applications. The tubes will be manufactured by an automatic welding processk from a flat-rolled alloy.This specification does not allow the use of filler metals. After welding and before the final heat treatment, the tubes must undergo cold-working . Mechanical properties such as tensile strength, yield strength, and elongation shall be examined accordingly. Each tube will also undergo a flattening test, flange test, as well as a hydrostatic, pneumatic, eddy current, ultrasonic, leak, and electric tests.
