Superalloy Gh1131 Plate/Coil/Rod/Bar/Pipe for High-Temperature Parts of an Aero Engine That Works 750 Degrees for a Long Time

Superalloy GH1131 plate/coil/rod/bar/pipe for High-temperature parts 
Product characteristics:
It is a high-performance iron-based superalloy strengthened by complex solid solution of tungsten, molybdenum, niobium, nitrogen and other elements, and the alloy has good hot working plasticity and welding cold forming process performance

Product application:
The product can be used to make rocket engines that work in a short time of 700-1000 degrees. High-temperature parts of an aero engine that works 750 degrees for a long time.

Product variety:
production of various specifications of plates, pipes, strips, bars, wires, wires, ring parts, flange forgings, etc. The maximum diameter of seamless ring parts is more than 5000mm, and the thinnest thickness of strip is 0.01mm

GH1131 is a high-performance superalloy reinforced by tungsten, molybdenum, niobium, nitrogen and other elements. The nickel content is about 28%, but its thermal strength level is different from that of GH3044 alloy.

GH1131 is a high-performance superalloy reinforced by tungsten, molybdenum, niobium, nitrogen and other elements. The nickel content is about 28%, but its thermal strength level is different from that of GH3044 alloy. The alloy has good hot-working plasticity, welding and cold forming process properties. The main products are cold-rolled plate, hot-rolled plate, bar, flat steel and wire rod. It can be used to manufacture high-temperature parts of rocket engines working at 700-1000 °C for a short time and high-temperature parts for aircraft engines working at 700 °C and 750 °C for a long time.

Heat treatment system
Hot rolled plate and cold rolled plate are air-cooled at 1130-1170°C; Bar: 1160°C±10°C, air cooling.

Breed status
Cold-rolled sheet, hot-rolled sheet, bar, welding wire, etc. Hot rolled and cold-rolled plates are supplied after solution treatment, pickling, straightening and trimming; The supplied rods are not heat treated; The welding wire is supplied in cold-drawn, heat-treated and pickled or semi-hard condition.

Melting and casting process
The alloy is produced by non-vacuum induction furnace plus slag remelting or arc melting plus slag remelting.

Special Requirements
The alloy is mainly used as a high-temperature component of rocket engines. On the aero engine, parts such as the adjustable nozzle shell and the afterburner adjustment have been manufactured and put into production. Compared with similar nickel-based alloys, the microstructure stability of the alloy against high temperature oxidation is poor, and the plasticity decreases at room temperature after long-term use at 700 ~ 900 °C, and the formability becomes worse.
