Durehete Applications
Durehete grades are specified across high-temperature rotating and pressure equipment. The 540–580°C service envelope covers steam-turbine casing bolting (HP and IP stages), gas-turbine compressor and casing bolts, supercritical / ultra-supercritical power-station main-steam bolting, and refinery fired-heater bolting where elevated-temperature creep resistance is the controlling design criterion.
Durehete High-Temperature Bolts (7 application classes)
Steam turbine HP/IP casing, gas turbine compressor and casing, supercritical and ultra-supercritical power-plant main-steam, refinery fired-heater bolting. Grade selection per service-temperature envelope.
