Product FEATURE
GH3044 is solid solution strengthened nickel-based antioxidant alloy, in the 900 ℃ below with high plasticity and moderate thermal strength, and has excellent oxygen and good stamping, welding process performance, suitable for the manufacture of aero-engine main combustion chamber at 900 ℃ below the long-term work of the main combustion chamber and combustion chamber components and heat insulation screen, guiding blade, supply varieties of plates, strips, wires, tubes, rods, and ring-shaped parts and so on. GH3044 ingot forging heating temperature of 1170 ℃ ± 10 ℃, final forging temperature of not less than 900 ℃. Slab rolling heating temperature 1190 ° C ± 10 ° C, sheet hot rolling heating temperature 1130 ° C ± 10 ° C, the final rolling temperature of not less than 800 ° C; sheet cold rolled total under pressure rate of about 30%. GH3044 plate has good process performance of stamping parts. Cold rolled sheet supply state of the limit of deep-drawn coefficient of K limit = 2.06.
Product application
After solid solution at 1200℃, it is basically single-phase austenite and a small amount of MC and M23C6 carbides. By 700 ~ 900 ℃ after long-term aging. MC change is not big, M23C6 was chain distribution in the grain boundary, when the growth of time, precipitation increased, the particle growth; At the same time in the crystal and the grain boundary and the WCr solid solution complementary precipitation, was granular, when the prolongation of time, the number of gradual increase in time, the size of the growing.
