Introduction

Nickel alloy 86 is a nickel-chromium-molybdenum alloy with good formability and weldability, exceptional resistance to scaling and oxidation at temperatures up to 1050°C (1920°F). It is a rare alloy due to the presence of cerium in its composition. It is a solid solution alloy, and hence used for high temperature applications.

The following section will discuss in detail about nickel alloy 86.
