Description about 301 stainless steel
301 (17Cr-7Ni-carbon) material: Compared with 304 steel, Cr, Ni content is small, tensile strength and hardness increase during cold processing, non-magnetic, but magnetic after cold processing. Uses: trains, aircraft, conveyors, vehicles, bolts, springs, screens.
The 301 stainless steel is a metastable austenitic stainless steel and has a fully austenitic structure under full solution conditions. Among the stainless steels, 301 is the steel that is most easily deformed 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, the steel has good rust resistance under atmospheric conditions. However, the corrosion resistance of the reducing media is poor, and the corrosion resistance of chemical media such as acid and alkali salts is poor. Therefore, it is not recommended for use in corrosive environments. 301 is mainly used in cold working conditions to withstand higher loads, but also to reduce equipment weight and rust-free equipment components. In addition, this steel is susceptible to work hardening when it is impacted by external forces, absorbing more impact energy and providing more reliable safety protection for equipment and personnel.
301 GB grade is 1Cr17Ni7304 GB code 0Cr18Ni9, so compare 301 to 304 steel, due to lower Cr and Ni content, so the corrosion resistance is greatly reduced. After cold rolling can improve the tensile strength. 301 was originally no magnetic, but After cold rolling, it will have magnetic properties.
