application:The 3j21 alloy was an old material in the mid-1960s and has been produced and applied for many years.
It is mainly used for wear-resisting, anti-corrosion, anti-seismic, non-magnetic, and high intensity of air use elastic components, such as shaft, wire, spring, spring and diaphragm.
It is also used in the production of special bearings, small shafts, ball bearings, stamping dies and cutting tools.
