About 2.4606 NiCr21Mo16W Alloy 686 UNS N06686 Forgings for Nuclear, FGD, Chemical Pump Parts, Valve Bodies, Rolled Rings Tube Sheets Jiangsu Liangyi

Jiangsu Liangyi is an ISO 9001:2015-certified nickel-alloy forging manufacturer in China supplying 2.4606 / NiCr21Mo16W (Alloy 686 / UNS N06686) open-die forgings and seamless rolled rings to nuclear, FGD, chemical, power and turbomachinery projects in India and worldwide, to ASTM B564 and DIN EN standards.

Why 2.4606 / NiCr21Mo16W for Indian nuclear, FGD and chemical projects

2.4606 is a single-phase Ni-Cr-Mo-W corrosion alloy with a exceptional localized-corrosion resistance (CPT/CCT >85 C, ASTM G48 C&D) giving superior resistance to oxidising and reducing acids, pitting and crevice corrosion, plus weld-HAZ stability from its ultra-low carbon. For India's nuclear build-out, thermal-power FGD systems and aggressive chemical/phosphoric-acid plants, it suits reactor-coolant-pump parts, FGD slurry pump components, severe-service valves and heat-exchanger tube sheets.

Documented deliveries

Nuclear (China): RCP casings, impellers and seal chambers in several 1000 MW PWR plants, RCC-M, 8+ years stable.

Chemical: valve balls, seats, bodies, PV nozzles and HX tube sheets service life from 6 months (316L) to 5+ years.

FGD: slurry pump casings, impellers, wear rings and spray nozzles, trouble-free 4+ years on ultra-supercritical units.

Turbomachinery: 1000+ compressor impeller forgings to API 617.

Product range for Indian buyers

Round/square/flat/rectangular bars; seamless and contoured rolled rings; valve balls, bodies, seats, stems, discs; pump casings, impellers, shafts, wear rings; PV nozzles, tube sheets, baffle plates, channel flanges; discs, hubs, blocks; pipes, tubes, casings.
