UNS Nickel 270

Profile

This page is mainly introduced the Nickel 270 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of Nickel 270,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
Wrought nickel and nickel-related alloys

A high-purity grade of nickel made by powder
metallurgy. It has a low base hardness and
high ductility. Its extreme purity is useful for
components of hydrogen thyratrons. It is also
used for electrical resistance thermometers.
