Sensing quenching steel generally has the following requirements: 1. The carbon containing amount of steel is determined by the working conditions of the parts, which can be 0.15% to 1.2% from W (c), which is the most basic requirement. 2. Steel should have austenitic crystal grains that ar...

1. Carbon (C) Carbon determines the hardness of the steel quenching, high carbon content, high quenching hardness, but is easy to quench. 2. Silicon (Si) steel eliminates the strength and hardening of the steel, and the sedative effect can be removed during steelmaking. 3. Manganese in mang...
