Duplex 2205 seamless rolled rings are used where a component requires the strength and corrosion-resistance balance of a duplex stainless steel. Ring rolling can provide a continuous annular form for offshore equipment, chemical process systems, pumps, valves and pressure-related assemblies. For this grade, process control is especially important because the final microstructure is part of the performance requirement.
2205 is not simply a stronger version of 316L. Its duplex structure and alloy chemistry provide different performance characteristics, and suitability depends on chloride exposure, temperature, pH, stress and design code. Confirm whether standard 2205 is sufficient or whether the service calls for super duplex 2507.
The preform, deformation schedule and cooling practice influence the final structure. Solution annealing and rapid cooling are normally controlled to meet the applicable material specification. The RFQ should identify any requirements for ferrite content, phase balance, corrosion testing or supplementary metallographic examination.
2205 has higher strength than many austenitic grades, which can influence cutting loads and tool life. State machining allowance, bore and OD tolerances, face flatness, concentricity and surface finish. For large sections, intermediate dimensional checks can help control the sequence from rough machining to final finishing.
Specify chemistry, tensile properties, hardness, heat-treatment records, traceability and dimensional inspection. Add UT, PMI, corrosion tests or phase-balance checks when required, with the relevant method and acceptance criteria. Include service conditions and the complete drawing in the inquiry.

Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
