Product Features

GH3044 is a solid solution strengthened nickel based antioxidant alloy with high plasticity and moderate thermal strength below 900 ° C, as well as excellent oxygen resistance and good stamping and welding process performance. It is suitable for manufacturing aviation engine main combustion chamber and afterburner components, as well as insulation screens and guide blades that work for a long time below 900 ° C. The supplied varieties include plates, strips, wires, tubes, rods, and annular parts. The forging heating temperature of GH3044 steel ingot is 1170 ° C ± 10 ° C, and the final forging temperature is not less than 900 ° C. The rolling heating temperature of slab is 1190 ° C ± 10 ° C, and the hot rolling heating temperature of thin plate is 1130 ° C ± 10 ° C, and the final rolling temperature is not less than 800 ° C. The total reduction rate of thin plate cold rolling is about 30%. GH3044 sheet has good stamping process performance. The limit deep drawing coefficient of cold-rolled sheet supply state is K-limit=2.06.

Application scope and field

After solid solution at 1200 ° C, it is basically single-phase austenite with a small amount of MC and M2C.. Type of carbide. After long-term aging at 700-900 ° C. There is not much change in MC, M2C。 Distributed in a chain like pattern at grain boundaries, with the increase of aging time, the precipitation amount increases and the particles grow; At the same time, WCr solid solution is supplemented and precipitated in the crystal and grain boundaries, appearing in granular form. With the extension of aging time, the quantity gradually increases and the size continues to grow.
