Abstract
HASTELLOY C-276 (UNS N10276) is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. This alloy is resistant to the formation of grain boundary precipitates in the weld heataffected zone, thus making it suitable for most chemical process applications in an as welded condition. So here we examine the corrosion behaviour of the weldment of Hastelloy C-276, which is welded by Gas Tungsten Arc Welding (GTAW) and Shielded Metal Arc welding (SMAW) by using the traditional corrosion testing method i.e immersion corrosion test. The corrosion test is conducted by using Green death solution that acts as the corrosion medium which is a mixture of acids. The solution is heated to boiling, 103 °C (217 °F), for 72 hours. Such a corrosive environment occurs at power plants. Corrosion rate was determined by using weight loss method. Results of the corrosion test were compared between the GTAW and SMAW samples. The microstructural analysis is made on weld zone, heat affected zone and base metal of both the welded samples.
