KX W.Nr.2.4683 Uns Light Rod Plate Structural Operating Temperature Range For High Temperature Alloy
Product Description and Application
W.N.2.4683 is also known as UNSR30188, Hayness 188,GH5188
W.N.2.4683 is solid solution strengthened cobalt base superalloy. Add 14% tungsten for solid solution strengthened and make the alloy have excellent high temperature thermal strength. Add high content chromium and trace lanthanum and make the alloy have good oxidation resistance at high temperature and satisfactory forming, welding and etc technological properties. It is suitable for the manufacture of aeroengine parts requiring high strength below 980℃ and oxidation resistance below 1100℃. The alloy is widely used abroad in the manufacture of high-temperature components of gas and missiles, such as combustor, tail nozzle and heat exchanger parts in the nuclear energy industry. The high temperature components that aero-engine combustion chamber flame cylinder and guide vane made of this alloy have passed long-term test and been put into production in China.
