N02201/Ni201

    

Introduction

Nickel 201 alloy is a commercially pure wrought alloy having properties similar to that of nickel 200 alloy, but with a lower carbon content to avoid embrittlement by inter-granular carbon at high temperatures.

It is resistant to acids and alkalis, and dry gases at room temperature. It is also resistant to mineral acids depending on the temperature and concentration of the solution.

The following section will discuss in detail about nickel 201 alloy.
