Corrosion-resistant and high-hardness alloy compos

摘要： Cr: 15.5 to 16.5 wt%, Mo: 7.5 to 15.5 wt%. In an alloy composition comprising Co: 0 to 30 wt%, Fe: 4.5 to 15 wt%, Cu: 0.5 to 4.0 wt%, the balance: Ni and unavoidably mixed elements, the crystal phase is in the phase It is a single phase, and by setting the Vickers hardness at room temperature to be 500 HV or more, a Ni-Co-Cr-Mo alloy in which corrosion resistance and abrasion resistance are compatible is obtained. Further, after homogenizing the ingot of the alloy having the above composition at 1100 to 1300 C. for 4 to 24 hours, the ingot is subjected to cold working at a compression ratio of 30 to 60%, and then in an temperature range of 300 to 600 C. , Aging treatment for 0.5 to 3 hours to obtain the Ni-Co-Cr-Mo alloy.
