Similarly, using nickel alloy (Ni60), we adjusted the ratio and composition of the metal to lower its hardness, which is used to produce threaded components with a hardness of HRC40-44 This not only ensures the corrosion resistance of nickel alloy products, but also greatly increases their wear resistance compared to other similar nickel alloys (HaC276 hardness HRC25). It is a high-quality alloy product used in strong acid environments.
