Corrosion-resistant superalloy fasteners for upstream, midstream, and downstream hydrocarbon processing. From wellhead bolts to subsea connectors and refinery reactor bolting.
Oil and gas fasteners face some of the most aggressive environments in engineering: sour gas with H2S, hot chloride brines, high-pressure hydrogen, and mixed acid streams. Hastelloy C-276 provides unmatched resistance to wet chlorine and reducing acids in chemical and refining processes. Inconel 625 handles seawater, sour gas, and high-temperature oxidation. Inconel 718 delivers NACE-compliant strength for wellhead and subsea connectors. Monel K-500 excels in seawater and hydrogen sulphide environments with controlled hardness per API 6A CRA practice.
