A CD4MCu Plug Valve is crafted from Duplex Stainless Steel CD4MCu alloy, which includes copper and molybdenum additives. It features cylindrical or conically tapered plugs for precise fluid flow control. Known for its high yield strength, hardness, toughness, and corrosion resistance, CD4MCu is designated ASTM A890 Grade 1A in both the ACI and ASTM systems, with UNS number J93370. This material belongs to the category of cast duplex stainless steels, characterized by moderately low ductility and relatively high tensile strength, making it ideal for demanding environments that prioritize corrosion resistance. Typical applications include offshore oil and gas, chemical processing, and marine environments.
