Metallurgical & Chemical

About Metallurgical and Chemical (M&C) Department:

Functions as premier R&D establishment for conducting research, evaluation, testing and standardization on materials (metals, alloys, paints, fuels, lubricants, rubber, plastics composites, welding consumables etc.) with the objective of employing the most efficient, cost effective and reliable material on Indian Railways. It functions as a consultant to Railway Board, Design Dtes, Zonal Rlys and Production Units in the areas of materials selection, upgradation of material, testing of material, indigenization, welding technology, foundry technology, NDT technology, Paint technology, and investigation into failures of components in service. Besides, it also imparts training to Rly personnel in the field of Non-Destructive Testing, Welding Technology, Corrosion Prevention and failure analysis to equip them with the latest development.
