STAINLESS CLAD STEEL EXCELLENT IN SEA WATER PITTING CORROSION RESISTANCE AND APPEARANCE

摘要

PROBLEM TO BE SOLVED: To provide a stainless clad steel excellent in sea water pitting corrosion resistance and appearance.;SOLUTION: The stainless clad steel excellent in sea water pitting corrosion resistance and appearance is a stainless clad steel obtained by using as a clad material, a stainless steel having a Pitting Index represented by Cr (mass%)+3.3 Mo (mass%)+16 N (mass%) of 40.0 or more, containing 10 to 40 ppm of B and having σ phase area percentage of a surface of 1.0% or less. The stainless clad steel excellent in sea water pitting corrosion resistance and appearance has glossiness in a rolling direction, a rolling vertical direction and rolling 45° direction measured at a measurement angle of 60° according to JISZ8741 "specular glossiness-measurement method" of each 60 or more.;COPYRIGHT: (C)2014,JPO&INPIT
