301 grade stainless steel is a common stainless steel with good corrosion resistance and high carbon content, which can be cold worked to various temperatures. Among stainless steels, 301 is the most easily strengthened by cold deformation. Through cold deformation processing, the strength and hardness of the steel can be improved, and sufficient plasticity and toughness can be retained. In addition, this steel has good rust resistance under atmospheric conditions, but poor corrosion resistance in reducing media and chemical media such as acid, alkali and salt. Therefore, it is not recommended for use in corrosive and harsh environments
