It has high strength, high toughness, good hardenability, stability against overheating, high white spot sensitivity, and temper brittleness. The weldability of steel is poor, so it needs to be preheated at high temperature before welding and stress relief treatment after welding. It is generally used in the quenched and tempered state, and can also be used as ultra-high strength steel after low temperature tempering or isothermal quenching
