ASTM B677 UNS N08904 Nickel Alloy Steel Tube
Overview
ASTM B677 is the standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes made from UNS N08904 (Alloy 904L). This standard specifies the requirements for the chemical composition, mechanical properties, dimensions, and tolerances of pipes made from UNS N08904.
Here are some key points covered in the ASTM B677 standard for UNS N08904:Chemical Composition: The standard specifies the required chemical composition of UNS N08904, including the percentages of elements such as nickel (Ni), chromium (Cr), molybdenum (Mo), copper (Cu), and others. These elements contribute to the corrosion resistance and mechanical properties of the alloy.Mechanical Properties: ASTM B677 defines the minimum tensile strength, yield strength, and elongation requirements for UNS N08904 pipes. These properties ensure the mechanical integrity and performance of the pipes in various applications.Manufacturing Process: The standard covers the methods of manufacturing, which include seamless and welded methods. It also outlines the process of cold working, which enhances the strength and durability of the pipes.
