Abstract:
The present invention provides a nonmagnetic high-hardness alloy having a Ni-based alloy composition containing; by weight %, C of 0.1% or less: Si of 2.0% or less; Mn of 2.0% or less; P of 0.03% or less; S of 0.01% or less; Cr of 30 to 45%; Al of 1.5 to 5.0%; and a balance of unavoidable impurities and Ni, the nonmagnetic high-hardness alloy being subjected to cold or warm plastic working and then ageing treatment, and a method for producing the nonmagnetic high-hardness alloy.
