Super Alloys, with the increasing demands of
today’s process industries comes the need for better
technology and more sophisticated equipment. Increasing
productivity and reducing downtime in process plants is
very desirable, as such more industries are focusing on
materials which will provide a longer life in service and
perform better under the harsh conditions found in the
oil, gas, chemical and petrochemical industries. Due to
has developed a strategic network of
internationally renowned suppliers of nickel alloy and
super alloy materials. This is because nickel alloys are
corrosion resistant, have a high temperature strength and
have special magnetic, and thermal expansion, properties.
Nickel Copper Alloys are used where a higher strength is needed than that of pure nickel. They are resistant
to corrosion in a wider range of environments than pure nickel, although for some specialist applications nickel
would be superior. However, nickel copper alloys have a
wide range of applications, such as in oil refining and
marine applications where a long, corrosion-free life is needed. Because of their excellent thermal conductivity,
they are often used in heat exchangers where sea water is
one of the fluids concerned.
Nickel Chromium Based Alloys are used extensively
where heat resistance or corrosion resistance is required.
In conditions that are less demanding, some nickel can be
replaced by iron to reduce the overall cost. Metals fail
at high temperatures by oxidation (scaling) and through a
loss of strength. Nickel chromium based alloys are
designed to resist these problems, although they are not
suitable for high temperature, sulphur rich environments.
Where corrosion resistance is an issue, molybdenum can be
used as an alloying addition.
