Nickel-based superalloy GH4145 Inconel X-750 bar tube plate

Short Description:

GH4145 alloy is a kind of corrosion-resistant, oxidation-resistant and high-strength precipitation hardening alloy. It is mainly a nickel-based superalloy that is aged and strengthened by γ”[Ni3(Al, Ti, Nb)] phase. It has good corrosion resistance and oxidation resistance below 980 ℃, and has high corrosion resistance below 800 ℃. It has good relaxation resistance below 540 °C, and also has good formability and welding performance. The alloy is mainly used to manufacture aero-engines that work below 800 °C and require high strength. Relaxation-resistant flat springs and Coil spring.The main supply form of the product:wire,strip,plate,bar,pipe.The minimum order quantity is 50kg.

GH4145 alloy is a kind of corrosion-resistant, oxidation-resistant and high-strength precipitation hardening alloy. It is mainly a nickel-based superalloy that is aged and strengthened by γ"[Ni3(Al, Ti, Nb)] phase. It has good resistance below 980°C. Corrosion and oxidation resistance, high strength below 800℃, good relaxation resistance below 540℃, good formability and welding performance, and excellent mechanical properties in low temperature environments. The alloy is It has good corrosion resistance and creep rupture strength under high temperature environment, good mechanical properties, and is widely used:
1. Manufacturing springs and bolts that work at high temperatures; rotor blades, impellers and other structural parts on gas turbines;
2. The thrust chamber on the rocket engine;
3. Thrust reverse device on the aircraft;
4. Large high-pressure vessel;
5. Elastic air sealing sheet, elastic sealing die sheet, rubber mechanical electric heating blade.

Chengyuan Alloy can supply various specifications of bars, forgings, ring parts, hot-rolled plates, cold-rolled plates, strips, pipes and wires of GH4145 grades. Plates and strips are generally supplied after hot rolling or cold rolling, annealing or solid solution, pickling and polishing. Bars, forgings and ring parts can be supplied in the forged or hot rolled state; they can also be supplied after forging and solution treatment; the bars can be supplied after solid solution and polished or turned.
