ASTM B865 UNS N05500 Nickel Alloy Steel Tube
概述
ASTM B865 is the standard specification for precipitation-hardening nickel alloy bars， forgings， and forgings stock for high-temperature service. This standard covers UNS N05500， which is a precipitation-hardening nickel-copper alloy commonly known as Alloy K500.
Here are some key aspects covered in the ASTM B865 standard for UNS N05500:Chemical Composition: The standard specifies the required chemical composition of UNS N05500， including the percentages of nickel (Ni)， copper (Cu)， aluminum (Al)， titanium (Ti)， and other elements. These elements contribute to the alloy's corrosion resistance， high strength， and ability to be precipitation hardened.Mechanical Properties: ASTM B865 defines the minimum mechanical properties such as tensile strength， yield strength， elongation， and hardness requirements for UNS N05500 bars， forgings， and forgings stock. These properties ensure the alloy's suitability for high-temperature service and its ability to withstand demanding operational conditions.Manufacturing Process: The standard outlines the methods of manufacturing UNS N05500 products， including hot working， cold working， heat treatment， and precipitation hardening. It provides guidelines for the various stages of production to achieve the desired mechanical properties and microstructure in the finished products.
