A study on the structure and properties of precipitation hardening non-magnetic die steel has been carried out with different alloy compositions and heat treatments. A new type of non- magnetic die steel with a hardness of 48 (HRC) has been successfully developed after aging at 700 ℃ and solution treatment at 1180℃. Its relative permeability is 1.0056, thus the steel is equivalent to existing non-magnetic steels, but the cost of it is lower. The wear test indicated that the wear resistance of it is 38% higher than that of some non-magnetic die steel.
