P22 Alloy Steel Hot Forged Rings , Hot Forged Discs And Flange Blanks

Jiangyin Fangyuan supplies P22 chromium-molybdenum alloy steel hot-forged rings, forged discs and flange blanks, with annealing or normalizing-and-tempering heat treatment and rough or proof machining options. Published product data describes large-format forgings for pressure equipment and industrial components, with final dimensions and inspection requirements confirmed against the purchaser's drawings and the governing material specification.

Available product forms include forged rings, forged discs and flange-type blanks. The supplier describes annealing or normalizing-and-tempering heat treatment, followed by rough or proof machining as required by the drawing and purchase specification.

The following composition is reproduced from the product listing and is consistent with the commonly published SA-335 P22 chemistry table. It is a grade reference, not a substitute for the heat analysis on the supplied forging's material test certificate.

For procurement, specify whether chemistry is to be assessed by heat analysis, product analysis or both, and identify the applicable standard edition. The listed chemistry alone does not establish mechanical properties, heat-treatment compliance or suitability for a particular pressure-boundary design.

The chemical limits shown on this page match the familiar P22 composition associated with ASTM A335 / ASME SA-335 Grade P22, a specification for seamless ferritic alloy-steel pipe for high-temperature service. ASTM A355, by contrast, is titled "Standard Specification for Steel Bars, Alloys, for Nitriding." These are different product standards and neither should be silently substituted for the forging standard governing a ring or disc.

• Forging drawing with OD, ID, height/thickness, machining allowance, datum scheme and dimensional tolerances.
• Material standard and edition, grade/class, melting route where specified, heat number and traceability requirements.
• Heat-treatment cycle, furnace uniformity/record requirements where applicable, and final condition.
• Mechanical test location, specimen orientation, tensile/yield/elongation requirements, impact testing temperature and acceptance values where required by the governing standard.
• NDE scope and acceptance criteria, including UT, MT or PT where specified by design code or purchaser.
• Machining stage, surface finish, edge preparation, marking and final dimensional inspection.

• 1 Material verification Review incoming billet or ingot identification, heat number, material documentation and chemistry before cutting.
• 2 Heating and hot forging Heat the stock under the approved forging procedure and form the ring or disc using the specified forging route and reduction ratio.
• 3 Heat treatment Apply the agreed annealing or normalizing-and-tempering route. Record the actual cycle and verify the final condition against the purchase specification.
• 4 Rough / proof machining Machine reference faces and dimensions to the agreed allowance or finished drawing. Record critical dimensions and surface finish.
• 5 Inspection and release Complete the specified chemical, mechanical, dimensional and NDE checks; compile traceable reports and identify the finished forging.

The company profile describes a 3,000 m² testing center with chemical analysis, metallography, spectrometry, mechanical-property testing and ultrasonic testing equipment. Its quality-control page also lists incoming-material, in-process and finished-product inspection activities.

For each order, the inspection and test plan should state which tests are included, who performs them, sampling locations, acceptance criteria and the reports delivered with the forging.

Jiangyin Fangyuan Ringlike Forging And Flange Co., Ltd. is a forging manufacturer based in Zhouzhuang Town, Jiangyin City, Jiangsu Province, China. The company profile states that it was established in 1993 and manufactures gear rings, flanges, main shafts, ring forgings, valve forgings and pressure-vessel forgings.

The published equipment list includes hydraulic presses from 800 t to 3,600 t, ring-rolling machines up to 5,000 mm, vertical and horizontal lathes, and CNC drilling equipment. The company profile describes approximately 600 employees, including engineering and technical personnel, and a dedicated testing center.

The ECER supplier profile displays ABS, CCS, BV, DNV, GL, KR, LR, NK, RINA, API-6A, API-17D, ISO 9001:2008, ISO 14001:2004 and PED-related entries. These are supplier-profile-level certificate listings. They do not establish that every listed approval is current or that each one covers this specific P22 forging. Buyers should verify the current certificate, legal holder, manufacturing site, scope, validity and product applicability for the contracted order.

The company identity and production facts in this module refer to Jiangyin Fangyuan Ringlike Forging And Flange Co., Ltd., the supplier named on the ECER profile associated with this product. They are not attributed to the separately named Indian company "Metal Forgings Pvt. Ltd."

NBD Trade Data identifies a company record under the name "JIANGYIN FANGYUAN RINGLIKE FORGING & FLANGE CO., LTD." with China exporter status, 42 records and eight buyers. The available summary is consolidated below; it represents recorded entries in that database, not every shipment made by the manufacturer.

The 2025 examples identify F316/F316L round-bar shipments, not P22 forged rings. These records support the existence of cross-border activity associated with the named company entity; they do not prove export of this exact P22 product, nor do they independently verify its performance or quality.

• Match the supplier's full legal name and address against the purchase contract, invoice, bank beneficiary and shipping documents.
• Ask for shipment references for the same product family, material grade and destination market where relevant.
• Verify the P22 material designation and forging standard separately from the company's general export activity.
• Cross-check any claimed shipment against bills of lading, customs declarations, certificates of origin and commercial invoices.

Supplier Trade Data Disclaimer: The table summarizes selected representative entries available in public trade-data databases and does not constitute the supplier's complete shipping history. Records are matched by supplier entity name and related naming variants and consolidated into high-level categories. Corporate spelling variations, group entities and duplicate registrations may affect matching. The information is for reference and is not a formal verification or endorsement of creditworthiness, qualifications or product quality. Buyers should independently verify specific transactions against original bills of lading, customs declarations and commercial invoices.

The following third-party and supplier-channel references are included as supporting context. They are not substitutes for material certificates, inspection reports or contractual technical specifications.
