Title:
Ni BASE ALLOY, FUEL INJECTION PART USING SAME, AND METHOD FOR PRODUCING Ni BASE ALLOY
Document Type and Number:
WIPO Patent Application WO/2018/221560
Kind Code:
A1
Abstract:
Provided are: a Ni base alloy having wear resistance equivalent to or exceeding that of existing high-carbon martensitic stainless steel, without detriment to the superior anti-corrosion properties 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 produce the Ni base alloy efficiently. The Ni base alloy contains, in % by mass, more than 0.1% but no more than 1.0% C, 30-45% Cr, 2-5% Al, and 0.5-3% V, with the remainder being made up of Ni and unavoidable impurities. The Ni base alloy preferably contains a Cr carbide which contains V, and the Ni base alloy is preferably characterized by the Cr carbide which contains V having a field of view surface area ratio of 5-30% in a field of view of 200000 µm2.
