What is 301 stainless steel strip ?

Among stainless steels, 301 stainless steel is the most susceptible to cold deformation and strengthening. 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 poor corrosion resistance in chemical media such as acids, alkalis and salts. Therefore, it is not recommended for use in harsh corrosive environments.
301 stainless steel is mainly used in a cold-processed state to withstand high loads, and it is hoped that the weight of the equipment and rust-free equipment parts will be reduced. In addition, this steel is prone to work hardening when impacted by external forces, which can absorb more impact energy and provide more reliable safety protection for equipment and personnel.
301 stainless steel is prone to work hardening when deformed, and is used in places requiring higher strength.
