Ni ALLOY CLAD STEEL SHEET EXCELLENT IN LOW TEMPERATURE TOUGHNESS AND HAZ TOUGHNESS OF BASE MATERIAL AND CORROSION RESISTANCE OF CLADDING MATERIAL, AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a Ni alloy clad steel sheet excellent in low temperature toughness and HAZ (Heat-Affected Zone) toughness of a base material and corrosion resistance of a cladding material, and a method of producing the Ni alloy clad steel sheet .;SOLUTION: The Ni alloy clad steel sheet excellent in low temperature toughness and HAZ toughness of a base material and corrosion resistance of a cladding material is provided which has a Ni alloy as the cladding material and a low alloy steel as the base material. The chemical component of the base material contains, by mass%, C:0.020 to 0.100%, Si:0.10 to 0.50%, Mn:0.75 to 1.80%, P:0.015% or less, S:0.0030% or less, Cu:0.01 to 0.50%, Ni:0.01 to 0.45%, Cr:0.01 to 0.50%, Mo:0.01 to 0.50%, Nb:0.005 to 0.080%, Ti:0.005 to 0.030%, N:0.0010 to 0.0060%, Al:0.070% or less, Ca:0.0010 to 0.0040% and the balance Fe with inevitable impurities.;COPYRIGHT: (C)2015,JPO&INPIT
