About Inconel 783 Alloy 783 UNS R30783 Forgings for Aerospace, Gas Turbine, Power Rings, Casings, Shrouds, Seals Discs Jiangsu Liangyi

Jiangsu Liangyi is an ISO 9001:2015-certified nickel-superalloy forging manufacturer in China supplying Inconel 783 / Alloy 783 / UNS R30783 (GH783) forged rings, casings, shrouds, seals, discs and bars to aerospace, gas-turbine, power-generation, oil & gas and petrochemical projects in India and worldwide, to ASTM B905 and AMS 5839.

Why Inconel 783 / R30783 for Indian aerospace, gas-turbine and power projects

Inconel 783 is an oxidation-resistant, low-thermal-expansion Ni-Co-Fe superalloy with a CTE roughly 20% below Inconel 718 and useful strength to ~704 C. For India's aerospace-engine and gas-turbine power programmes, R30783 suits clearance-control and containment rings, casings, shrouds and seals where tight running clearances must be held across thermal cycles to protect efficiency.

Documented capability

Aerospace & gas turbines: containment and clearance-control rings, casings, shrouds and seals for compressor, turbine and exhaust sections.

Power generation: seal/shroud rings and casings needing dimensional stability under cyclic heating.

Oil & gas / petrochemical: high-temperature, size-stable parts.

Product range for Indian buyers

Round/square/flat bars; seamless rolled rings (OD to 4,000 mm); clearance-control and containment rings, casings, shrouds, seals; forged hubs, sleeves, shells, hollow bars, discs; custom forgings.

Material data

Chemistry (typical, wt%): Ni 2630, Co 2630, Fe bal, Al 5.06.0, Nb 2.53.5, Cr 2.53.5, Ti 0.40, C 0.03 (low Cr keeps CTE low). Heat treatment: three-phase age (solution ~1121 C + beta age ~845 C + age ~718621 C). Tested per ASTM E8/E10.

Standards & quality

Manufactured to ASTM B905, AMS 5839 (billet AMS 5940); full NDT (UT/MT/PT/RT); EN 10204-3.1 MTRs; full traceability. Inconel 783, Alloy 783, UNS R30783 and GH783 are the same grade.

Commercial & logistics

Lead time by project; FOB Shanghai / CIF to Nhava Sheva, Mundra, Chennai, Kandla, Visakhapatnam.
