IN362361: An erosion resistant steel for underwater components of turbine hydrogenerators and process for producing the same

The invention relates to erosion resistant steel and a process for the preparation thereof. The composition of the invention results in an alloy that has unique composition for multiphase steel. The alloy has advantage of higher impact toughness values both at room temperature and sub-zero temperature. The developed alloy also has higher cavitation resistance compared to the cast 13%Cr-4%Ni stainless steel. The steel product exhibits erosion resistant properties useful for the development of underwater components of turbine hydro generators.
