Effect of alloying on the corrosion resistance of valve steel 55Kh20G9AN4
In the development of alloy steels for exhaust valves in engines operating on light (gasoline) and heavy (diesel) fuels one must take into consideration the effect of alloying elements on the corrosion resistance of the steel in the respective combustion products.
When the steel is alloyed with molybdenum (to increase its heat resistance) it must also be alloyed with elements improving its corrosion resistance in order to suppress the negative effect of molybdenum on the corrosion resistance.
