Good plasticity and toughness, easy to be formed by cold and hot processing, good machinability after normalizing or cold processing, good weldability, no temper brittleness, poor hardenability and hardenability.. Parts with low stress and high toughness are required for manufacturing, such as car body, storage tank, deep-drawn utensils, pipes, gaskets, etc., which can be used for cold rolling, cold stamping, cold heading, cold bending, hot rolling and other processes, as well as carburized parts and carbonitriding parts with low core strength.
