    Pitting Corrosion

    304H is an 18-8 stainless with elevated carbon and coarser grain structure to increase high temperature strength. Useful up to 1500°F. 304 / 304L. ... What is pitting corrosion and how does it happen? ... where PRE = %Cr + 3.3 * %Mo + 16 * %N. Increasing resistance to pitting (and crevice corrosion) is found as the PRE increases. Typical PREs ...

    Slicklines with high strength and corrosion resistance ...

    For service in high-temperature sour oils and gas wells. Very good resistance to stress corrosion cracking (SCC) in H 2 S, chloride and CO 2 environments. Very good resistance to pitting and general corrosion.

    Assessing the Pitting Corrosion Resistance of Oilfield ...

    The pitting corrosion resistance of four Ni alloys typically used in oilfield technology was electrochemically determined in 80,000 mg/L chloride solutions at temperatures up to 150°C. It was confirmed that the pitting corrosion resistance of these alloys at elevated and high temperatures is strongly influenced by its molybdenum content.
