Potential materials

High-temperature corrosion control first requires a thorough understanding of the operating conditions of the application in question: working temperatures, risk of overheating, types of corrosion likely to occur (including those that may occur during commissioning, shutdown or shutdown of installations), mechanical stresses. The table at 1 can be used as a guide in selecting potential materials according to the corrosion modes encountered.

On the other hand, you need to be familiar with the chemical, mechanical, forming and assembly properties of the materials available on the market. This enables an initial selection to be made, taking into account mechanical and economic requirements, on the basis of more or less empirical criteria...
