GH128 process performance and requirements
1, forging ingot furnace temperature no higher than fashion 700 °C, the final forging temperature greater than

900 °C

2, the average grain size and the degree of deformation of the alloy forgings, the final forging temperature are closely related.

3, the alloy can be used welding, spot welding, seam welding methods such as welding

GH128Application
GH128 suitable for the manufacture of 950 °C under long-term harm aviation engine combustion liner, after burner casting, flaps and other high-temperature

components, the main products for cold-rolled sheet, also can supply hot rolled plate, bar, forgings, wire and tubing.
