High Temperature Resistance
Chromium-Molybdenum composition ensures stability at elevated temperatures.
Enhanced Heat Transfer
Solid fin design increases external surface area, improving energy recovery in HRSGs.
High Strength Under Pressure
Alloy steel withstands thermal cycling and high-pressure steam environments.
Corrosion & Oxidation Resistance
Excellent resistance to oxidation and scaling in boiler exhaust gas atmospheres.
Long Service Life
Reliable performance over extended operation cycles in harsh boiler conditions.
Used primarily in Heat Recovery Steam Generator (HRSG) systems, especially in:
Combined-Cycle Power Plants
Gas Turbine Exhaust Recovery
Waste Heat Boilers
Superheater and Reheater Sections
Industrial Steam Recovery Units
Typically installed in superheater, reheater, or evaporator sections of HRSGs where high thermal efficiency and long operational life are required.
