AUSTENITIC STAINLESS CLAD STEEL PLATE EXCELLENT IN LOW TEMPERATURE TOUGHNESS OF BASE MATERIAL AND HAZ TOUGHNESS, AND CORROSION RESISTANCE OF CLADDING METAL AND PRODUCTION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an austenitic stainless clad steel plate excellent in corrosion resistance of a cladding metal, HAZ (Heat-Affected Zone) toughness, and low temperature toughness, in particular, brittle fracture arresting properties of a base material, and to provided a production method of the austenitic stainless clad steel plate.;SOLUTION: The austenitic stainless clad steel plate excellent in low temperature toughness of a base material and HAZ toughness, and corrosion resistance of a cladding metal is provided in which an austenitic stainless steel is used as the cladding metal and a low alloy steel is used as the base material. In the austenitic stainless clad steel plate, the base material contains, by mass%, C:0.02 to 0.10%, Si:0.10 to 0.50%, Mn:0.75 to 1.80%, P:0.015% or less, S:0.003% 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 0.08%, 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
