4.Characteristic
Medium-carbon high-strength carbon structural steel with high strength and hardness after quenching, the steel has mediummachinability, low cold deformation plasticity, poor weldability, no temper brittleness during heat treatment, but lowhardenability, and critical diameter in water 13 * 30mm, and there is a tendency to crack during water quenching. This steel isusually used after heat treatment such as normalizing or quenching and tempering, or high-frequency surface quenching.
