Fenicro®330 – Alloy 330

GENERAL INFORMATION

Fenicro®330 are alloys on the basis of solid solution of nickel-iron-chrome with addition of 2% silicon

Fenicro®330 is characterized with:

- good corrosion and scale resistances;

- excellent resistance to carbonizing, as well as to variable carbonizing-oxidizing atmospheres;

- good mechanical properties with high strengths at the increased temperatures.

Nature of structure

Fenicro®330 is an alloy on the basis of solid solutions in which a small amount of nitrides and carbides of the titan, carbonitrides are located in an austenitic matrix.

 

Corrosion resistance

This alloy nickel-chrome-iron with 2% of silicon is heat-resistant universal material. It has good corrosion resistance to about 1000°С, especially in variable conditions of heating and cooling. He has excellent resistance in relation to carburizing and in these conditions is applied in the industry in large volume. The good firmness in the atmosphere of nitrogen with the low content of oxygen does it suitable for application among split ammonia

Oxidation


Fenicro®330 has good corrosion resistance and resistance to scale formation up to about 1000°C (1850°Р). Each formed oxide film strongly grabs; especially in cyclic conditions of heating and cooling

 

Сarbonization

Alloy shows excellent resistance to carbonizing and is widely applied in the industry in such conditions. In the variable carbonizing and oxidizing conditions it has resistance against "green decay"
