DESCRIPTION
ХН60ВТ – is a special heat-resistant alloy based on nickel and chromium additionally alloyed by tungsten and titanium. It has such properties as infusibility, ductility and high electrical resistance and corrosion resistance. Melted in open electric furnaces and by using a plasma-arc remelting.
Main application of ХН60ВТ – details of combustion chambers, afterburners and other parts operating under temperatures 1000-1100°C.
