Inconel alloy 718 was discovered in 1980s for downhole apparatus. The need for meeting high pressure gas wells demands a high strength alloy with excellent corrosion resistance to gas containing high carbon dioxide and hydrogen sulphide for completion apparatus. The superalloys like Hastelloy C-276 were available and provided outstanding corrosion resistance to the anticipated fluids. … Continue reading Inconel Alloy 718 for oil and gas industry
