Nimonic Alloy 263 Chemical Composition, Grades, Table and Pdf

Nimonic Alloy 263 is a high tempering nickel based alloy that have a very good strength and corrosion resistance properties which are highly desirable for high temperature applications. There are generally nickel, chromium, cobalt, and other elements in the chemical composition of their alloys, and the mechanical properties are more outstanding. Grades of Nimonic Alloy 263 may be different from one another, and their composition is modified according to certain requirements as well as a heat treatment. A key component that facilitates the selection of the appropriate Nimonic Alloy 263 by the engineers and the researchers is a comprehensive table which provides the details of chemical composition, grades, and properties. A PDF document presenting this information gives the convenience of access and reference for people in aerospace, automotive and other industries were the high-temperature stability and reliability are vital.

Nimonic Alloy 263 Chemical Composition And Grade Table

Nimonic Alloy 263, a nickel-chromium-cobalt alloy of superior class is all-rounded in its strength and corrosion resistance, hence the ability to withstand high temperatures. Nickel is the main component of the alloy, usually 53%, followed by chromium (20-21%), cobalt (19-21%), molybdenum (5.60-6.10%), titanium (1.90-2.40%), aluminum (0.80-1.20%), and maximum 1. Because of that, this alloy can retain its mechanical properties at elevated temperatures and used for such components as gas turbine engine, industrial furnace and aerospace. Nimonic Alloy 263 is offered in various grades which are designed for particular purposes in high load working conditions.
