Title:
Ni BASE ALLOY, FUEL INJECTION PART USING SAME, AND METHOD FOR PRODUCING Ni BASE ALLOY
Document Type and Number:
WIPO Patent Application WO/2018/221561
Kind Code:
A1
Abstract:
Provided are: an Ni base alloy having wear resistance equivalent to or greater than that of existing high-carbon martensitic stainless steel, without detriment to the superior corrosion resistance and non-magnetic properties which are characteristic of Ni base alloys; and a method for producing Ni base alloy, with which it is possible to efficiently produce the Ni base alloy. The Ni base alloy contains, in % by mass, 30-45% Cr, 2-5% Al, and more than 0.1% but no more than 1% B, with the remainder being made up of Ni and impurities. The Ni base alloy is preferably characterized by the Cr boride having a field of view surface area ratio of 5-30% in a field of view of 200000 µm2.
