1050 structural steel
Detailed description:
High strength carbon structural steel with moderate machinability, low cold deformation plasticity, poor weldability, no temper brittleness during heat treatment, but low hardenability. The critical diameter in water is 13 * 30mm, and there is a tendency for cracking during water quenching. This steel is usually used after heat treatment such as normalizing or quenching tempering, or high-frequency surface quenching.
