Pulled fresh from our DLX labs, GH1140 is a smartly balanced Fe-Ni-Cr superalloy with nickel at 35-40% anchoring the high-temp stability, chromium 20-23% forging a tough oxide barrier against scaling, and iron as the economical base (balance) for that workhorse vibe. The strength squad? Molybdenum 2-2.5% and tungsten 1.4-1.8% for solid solution toughening, locking dislocations under load, while aluminum 0.2-0.6% and titanium 0.7-1.2% spark precipitation hardening for creep-crushing gamma-prime phases. Carbon's dialed to 0.06-0.12% to boost toughness without carbides, silicon ≤0.8% and manganese ≤0.7% for deox, plus tight P/S limits (≤0.025/0.015%) to dodge brittleness. Cerium ≤0.05% sneaks in for grain refinement. Density? A practical 8.0 g/cm³, keeping designs light yet robust.

Mechanically, it's versatile. Annealed, tensile strength hits 600-800 MPa, yield 250-350 MPa, with 40-50% elongation for smooth wire drawing into 0.5-10mm gauges. Heat-treat it – solution anneal at 1050-1100°C water quench, then age at 700-750°C for 8-10 hours – and tensile climbs to 1000-1200 MPa, yield 800-900 MPa, holding 500 MPa at 650°C with under 1% creep in 1000 hours. Fatigue life? Over 10^7 cycles at 400 MPa, thanks to fine precipitates. Oxidation? Stellar up to 750°C in air, forming adherent Cr2O3-Al2O3 layers that resist spallation. Thermal conductivity ~14 W/m·K at RT, expansion 16 x 10^-6 /°C – tuned for aero cycles without warping. Corrosion shines in hot gases and sulfides, though coat for chlorides. Weldable via GTAW with matching filler (preheat 150°C, PWHT age), machinable at 20-30 m/min with carbides. At DLX, we vacuum-induction melt for sub-ppm purity, exceeding GB/T standards – and it's 92% recyclable, fitting our green alloy push.
In a word, GH1140 blends Chinese ingenuity with global-grade endurance – cost-effective muscle for aerospace heat wars.
GH1140 wire isn't lab-bound; it's out battling in aero hotspots. Turbine combustors? Our specialty – coiled into liners and swirlers that endure 800°C flames without cracking, boosting efficiency in jet engines. We've wired up blade roots for compressor stages, where vibration and heat tag-team, cutting failures 35% for overhaul shops. Industrial aero derivatives love it for transition ducts in gas turbines, resisting sulfidation in fuel mixes.
High-temp fasteners? Bolts and rivets from our wire clamp hot sections tight, holding torque at 600°C without relaxation. Aerospace forgings use it for discs and shafts, leveraging age-hardening for 20,000-hour lives. Beyond pure aero, it's in furnace parts for engine testing rigs, enduring cyclic oxidation. At DLX, we customize: ultrafine wires for sensors, heavy for structural ties – all cert-ready for FAA/CAAC quals. It shaves 15-25% weight off legacy irons while quadrupling creep life, amping fuel savings in everything from fighters to civvy liners. If your design dances with 700°C+ demons, GH1140 wire from DLX keeps the rhythm steady.
