CORROSION RESISTANCE :

Since most high-temperature materials are optimised with regard to strength and corrosion resistance at elevated temperatures, their resistance to electrochemical low-temperature corrosion may be less satisfactory.
Components made of high-temperature material should therefore be designed and operated so that acid condensates are not formed, or at least so that any such condensates are drained away. 

APPLICATIONS :

• Tubes
• Pressure vessels
• Iron, steel, and non-ferrous industries
• Engineering industry
• Energy conversion plants
• Cement industry
