The advanced super-austenitic stainless steel INCOLOY alloy 27-7MO is employed in oil field extraction. Despite its more economical price, this alloy still relies on a combination of elements to give it corrosion resistance, high strength and good fabricability. The inclusion of molybdenum (6.5-8%), chromium (20.5-23%) and nitrogen (0.3-0.4%) helps to resist pitting and crevice corrosion. The nickel (26-28%) also increases resistance to reducing media and, along with the nitrogen, helps with resistance against stress corrosion cracking and attack by caustic media. This gives the alloy good performance in mixed acid environments, which is useful in the oil and gas industry.
