In modern industrial world, engineering components are prone to more rapid surface degradation such as erosion-corrosion, overheating, wear, solid particle abrasion, high temperature corrosion, etc. Due to above surface degradation, major problems causes tube wall thinning, results in premature failure of the super heater and reheater tubes. Alloys used at high temperature should possess good mechanical properties along with erosion - corrosion resistance. The present study behavior of boiler steel ASTM-SA213 T-22 (used in most of the power plants in the Northern India) has been investigated...
