Charging racks and fixtures
Charging racks made from heat resistant steel alloys
Charging racks made from heat-resistant steel alloy for charging aircraft landing gear parts made from 300 M material. The addressed parts become austenitized in AMS 2750 E furnace class 2 atmosphere furnaces and quenched in large volume oil quench tanks.
Charging racks made from carbon ﬁbre composites (CFC)
CFC charging racks are used, for instance, in high-vacuum furnaces for solution annealing of Nibase alloys. The strength and dimensional stability of the CFC racks at high temperatures is excellent. The charging rack shown is used for the heat treatment of diﬀusers from aircraft turbines, so that the heat treatment can be carried out without deformations on the parts loaded on the rack. Heat-resistant steel charging racks are not suitable for this type of application, because of their relatively high degree of distortion at high temperatures.
