Title:
FE-NI-CR ALLOY, FE-NI-CR ALLOY STRIP, SHEATH HEATER, METHOD FOR PRODUCING FE-NI-CR ALLOY, AND METHOD FOR PRODUCING SHEATH HEATER
Document Type and Number:
WIPO Patent Application WO/2017/208563
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an Fe-Ni-Cr alloy that exhibits excellent surface characteristics and that enables formation of a blackened coating having excellent blackening characteristics and an excellent resistance to peeling. In order to achieve this purpose, the present invention is characterized by having a composition that comprises, as mass%, C, Si, Mn, P, S, Cr, Ni, Mo, Co, Cu, N, Ti, Al, O, and H with the remainder being Fe and unavoidable impurities, and that satisfies formulas (1) to (4). T1 = 11 × [%N] + 0.1 ... (1) T2 = -39 × [%N] + 1.0 ... (2) A1 = 7.5 × [%N] + 0.1 ... (3) A2 = -42.5 × [%N] + 1.0 ... (4) Here, [%M] represents the content (mass%) of element M in the alloy, and T1, T2, A1, and A2 satisfy the relationships T1 < [%Ti] < T2 and A1 < [%Al] < A2.
