  • Quenching is a common heat treatment process. It is the metal heat treatment process in which the what is gb t 4171 q355nh weather steel for welded structure metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between what is gb t 4171 q355nh weather steel for welded structure strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
