SeAH CSS offers a specialized materials line for oil refining and petrochemical plants, engineered to handle severe corrosion, high temperatures, and harsh chemical exposure. Their RefineChem Material Series includes super-austenitic steels (e.g. 904L, 6Mo / S31254), duplex and super-duplex steels, and several nickel alloys (Ni-200/201, 400, 600, 601, 800H, 825).

These materials are used to fabricate corrosion-resistant pipes, fittings, valves, and other critical components that must withstand long-term exposure to aggressive process fluids & environments. SeAH’s integrated steelmaking, forging & finishing processes ensure material purity, uniform microstructure, precise dimension control, and certifications required for petrochemical service.
