Abstract

Carbon- Manganese Steels are used in boilers and pressure vessels in thermal power plants as standard high temperature structural steels. These Carbon- Manganese Steel weldments are prone to corrosion at elevated temperatures in presence of vanadium, chloride, sodium or sulfide ions at elevated temperature operating conditions. The high temperature weight gain kinetics is studied using Na2SO4- V2O5 molten salt coated on welded and unwelded sample. SEM/ EDAX and XRD analysis has been carried out for the surface analysis of corroded samples
