Quenching

Quenching is a process used in metallurgy to rapidly cool hot metal, typically by immersing it in water, oil, or another coolant. This sudden cooling alters the metal's internal structure, making it harder and stronger. Quenching is commonly employed after heating metal to high temperatures to enhance its mechanical properties. However, it can also induce stresses or cracks if not done properly. Overall, quenching is a controlled method to modify metal characteristics, improving its performance for various industrial applications.
