Product Details

Introduction

Super alloys have the capacity to function at very high temperatures and severe mechanical stress. They also have good creep and oxidation resistance. They can be formed in different shapes. They are subjected to solid-solution hardening, work hardening, and precipitation hardening for increasing their strength. There are three types of super alloys, namely cobalt-based, nickel-based, and iron-based alloys.
