Ni-BASED ALLOY, Ni-BASED ALLOY POWDER, NI-BASED ALLOY MEMBER, AND PRODUCT PROVIDED WITH Ni-BASED ALLOY MEMBER

摘要

Provided are a Ni-based alloy that can be melted and solidified and that has superior corrosion resistance and abrasion resistance, a Ni-based alloy powder, a Ni-based alloy member, and a product provided with the Ni-based alloy member. This Ni-based alloy having superior corrosion resistance and abrasion resistance contains, in mass%, 8.5-23.0% of Cr, 8.5-27.0% of Mo, 0.5-2.5% of Ta, 15.0-51.0% of W, and 1.0-3.5% of C, the remaining portion being Ni and unavoidable impurities, wherein the mass ratio Ni : Cr : Mo of Ni, Cr, and Mo is 2.5 to 3.5 : 1 : 1.0 to 1.5.
