Can we hardened p 20 steel up to 50-52 hrc?

Yes, P20 steel can be hardened to a hardness of 50-52 HRC through appropriate heat treatment processes, such as quenching and tempering. However, achieving this hardness level may require specific alloying elements and controlled heating and cooling rates. It's important to note that while P20 steel can attain this hardness, its toughness and ductility may be compromised at higher hardness levels. Always consult material specifications and guidelines to ensure optimal results.
