Why Haynes 188 / UNS R30188 for Indian high-temperature projects

188 is a cobalt-base Co-Ni-Cr-W solid-solution superalloy with lanthanum, giving excellent strength, outstanding oxidation resistance to 1,095 C, very good sulfidation resistance and excellent post-exposure ductility. For India's gas-turbine, aerospace and power sectors, R30188 suits combustors, transition ducts, afterburner components, nozzles and rings.

Documented capability

Gas turbines/aerospace: combustor cans, transition ducts, afterburner/nozzle components, seal/combustor rings, turbine components.

Power generation: high-temperature ring and structural forgings.

Industrial high-temperature: furnace and thermal-processing forgings.

General high-temperature: shafts, discs, hubs, sleeves, custom forgings.

Product range for Indian buyers

Forged bars, shafts; seamless rolled rings; combustor and transition-duct forgings; afterburner and turbine components; seal and combustor rings; nozzles, discs, hubs, sleeves.
