Document Type and Number:
WIPO Patent Application WO/2020/050229
Kind Code:
A1
Abstract:
The present invention provides an iron-based alloy having excellent corrosion resistance and high strength, and a method for producing the iron-based alloy. An iron-based alloy of the present invention includes Cr: 10-22 mass%, W: 1-12 mass%, and C: 0.1-2.3 mass%, with the balance being unavoidable impurities and Fe, and is made of a cast material having a structure essentially composed of austenite, or, a quenched material having a structure essentially composed of martensite, and in which carbide is precipitated. Additionally, the iron-based alloy may include Cu: 0.5-6 mass%, and/or, Ni: 0.5-2.5 mass%, and at least one among Al, Mo, and Si: 1-3 mass%.
