Ni-Based CW6MC: Effect of the Internal Revert Recycle on the Soundness of the Alloy

Abstract The CW6MC alloy is a nickel-based used to withstand acidic environments, especially in the oil and gas industry where it production of valves, impellers, pipes. This foundry counterpart best known A625 for plastic deformation. Regarding alloys, scrap market like that case steel has not yet been established, therefore, foundries, generally comes from internal recycling (casting waste, feeders, sprues, runners, etc.) be certain origin quality material. In this work, four castings with different percentage recycled content (0%, 30%, 70%, 100%) were produced accordance technical specifications analysed evaluate effect on final chemical composition, microstructure, mechanical properties corrosion resistance. Following analyses carried out, was determined amount acceptable (of those analysed) without compromising material corresponds 30%.
