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 this trend VENUS 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.
