Ni—Fe—Cr alloy and engine valve welded with the same alloy |
摘要 |
A hard-facing alloy having impact resistance, wear resistance and hot corrosion resistance and containing Fe which is a bountiful resource and inexpensive is provided. Provided are: a Ni—Fe—Cr alloy containing 0 to 20.0 mass % of Mo, 8.0 to 40.0 mass % of W, 20.0 to 40.0 mass % of a total amount of Mo and W, 20.0 to 50.0 mass % of Fe, 12.0 to 36.0 mass % of Cr and 1.0 to 2.5 mass % of B, and the remainder being Ni and unavoidable impurities; and an engine valve welded with the same alloy. The above Ni—Fe—Cr alloy can further contain 15 mass % or less of a total amount of elements selected from Co, Mn, Cu, Si and C, in such cases, 15.0 mass % or less of Co, 5.0 mass % or less of each of Mn and Cu, 2.0 mass % or less of Si and 0.5 mass % or less of C are preferred. |
