The last stage blades of the steam turbine are prone to water corrosion, and the failure of the blades leads to the unsafe operation of the steam turbine. The stellite alloy blade anti-corrosion sheet properly solves the problem, and the stellite alloy anti-corrosion sheet is welded to the blades by brazing. , effectively prevent the water corrosion of the steam turbine blades, and improve the safety and economy of the normal operation of the steam turbine.
Stellite Cobalt Alloy Bearing Bushing For Steam Turbine
Due to the special working environment of the steam turbine's pipeline valve bushing, the bushing is required to have good high temperature resistance and steam corrosion resistance. Stellite alloy solves the above problems very well. The temperature of the steam transported by the steam turbine is very high. And it is corrosive to valves and pipes, stellite alloy bushings can reduce downtime and replacement cycles.
1. Stellite alloys have higher melting points than nickel (or iron) alloys ,This gives them the ability to absorb stress to a higher absolute temperature .
2. Stellite alloys give superior hot corrosion resistance to gas turbine atmospheres , this is due to their high chromium content.
3. Stellite alloys show superior thermal fatigue resistance and weldability over nickel alloys .
---Excellent wear and corrosion resistance even at high temperature up to 800℃
