301 Stainless Steel Pipe
301 stainless steel pipe is a metastable austenitic stainless steel that has a complete austenitic structure under full solid solution conditions. 301 is the steel type that is most easily strengthened by cold deformation among stainless steels. The strength and hardness of the steel can be improved through cold deformation processing while retaining sufficient plasticity and toughness. In addition, this steel has good rust resistance under atmospheric conditions. 301 is mostly used in the cold working state for equipment parts that can withstand higher loads, reducing the weight of the equipment and making it rust-free. In addition, this steel is inclined to work hardening when impacted by external forces and can absorb more impact energy, providing more reliable safety protection for equipment and personnel. However, 301 stainless steel pipe has poor corrosion resistance in chemical media such as acid, alkali and salt, so it is not often used in harsh corrosive environments.
