KX Hayness 188 Uns Light Rod Plate Structural Operating Temperature Range For High Temperature Alloy
Product Description and Application
Hayness 188 is also known as UNSR30188, W.N.2.4683,GH5188
Hayness 188 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.

- Corrosion Resistance
The alloy can be circulating test at 900℃ ↔260℃ for 200h dynamic
thermal corrosion test,corroded by gas in the combustion device.
The alloy corrosion resistance is better than GH3536 alloy in
polluted environment containing Na2SO2 and NaCl
