Duplex Steel Forged Circle

Neptune Alloys is a trusted Duplex Steel Forged Circle Manufacturer offering high strength corrosion resistant circles made from dual-phase stainless steel. These forged circles are used in industrial components such as valve blanks, flange bases, pressure discs, and heavy-duty washers where mechanical load and corrosion exposure are common. Duplex steel combines ferritic and austenitic structures, giving these circles greater yield strength and better crack resistance. Their ability to withstand acidic and saline environments makes them a reliable choice for marine oil, gas, and chemical processing equipment. 

Preferred in precision machining and high load systems, these forgings are manufactured as per ASTM A182 and are suitable for B2B bulk projects that demand dependable metallurgy. Each circle is produced through open die forging or ring rolling and then machined to precise dimensions. Finishes include rough machined, polished, or custom cut surfaces depending on usage. Duplex steel forged circles are often used in pressure retaining equipment pump assemblies and structural flanges that require long term durability. Test certifications and tailored packing options are provided with each order to support industrial procurement needs.
