Salient Technical Feature including Competing Feature |
The alloy steel has multiphase steel and developed based on TRIP effect; hence can be used at room temperature as well as lower temperatures. The steel is developed through normal casting and heat treatment process. Itl has similar hardness and tensile strengths as that of presently used cast 13%Cr-4%Ni steel and has higher impact toughness (3 times as that of the 13%Cr-4%Ni) at room temperature as well as zero degree temperature. This steel exhibits higher erosion resistance as well as cavitation resistance as required for underwater components of turbine hydro generators |
