20NiCr14 steel has good hardenability and uniform strength in a large cross-section. After quenching and tempering, it has good comprehensive mechanical properties. Good machinability, moderate cold deformation plasticity and weldability. It has the sensitivity of forming white spots and the tendency of temper brittleness in high temperature tempering.
