Duplex Steel Forged Circle Manufacturers In India

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.

Frequently Asked Questions

What are Duplex Steel Forged Circles used for?

They find application mostly in high-stress conditions like offshore platforms, marine machinery and chemical reactors. Due to their strength and resistance to corrosion, they are suitable to be applied in aggressive environments with chlorides or sulfide stress. Their stable mechanical properties make them suitable for application in flanges, rings and other pressure-retaining components.

How are Duplex Steel Forged Circles tested for quality?

Each forged ring is subjected to ultrasonic testing, mechanical testing and chemical testing for reliability. Surface inspection is done to identify scale, cracks and finish consistency. All the tests are reported and handed over to clients along with Material Test Certificates (MTCs) and third-party inspection reports if needed.

Can I request custom diameters or heat treatments?

Yes, we provide complete customization such as forged diameter, surface finish (machined or rough turned) and special heat treatment like annealing or quenching. We produce to international standards like ASTM, ASME and EN, meeting special project orders. Lead times are minimized with ready-to-forge stock and in-house machining facilities.
