An Erosion Resistant Steel for Underwater Components of Turbine Hydrogenerators and Process for Producing the Same

Manufacture of  errosion resisitant steel for underwater components

As an underwater corrosion component.

• The multiphase steel comprising of martensite, austenite and bainite having high resistance against erosion due to silt impingement and cavitation can be employed as underwater components in hydroturbines.
• The alloy will have higher impact toughness values both at room temperature and sub-zero temperature.
• This alloy will have higher cavitation resistance compared to the cast 13%Cr-4%Ni stainless steel.
