Title:
CLAD STEEL PLATE
Document Type and Number:
WIPO Patent Application WO/2019/132039
Kind Code:
A1
Abstract:
The present invention provides a clad steel plate having a plurality of regions in layered form, the plurality of regions having differing compositions in the plate thickness direction, and the clad steel plate also having excellent yield and high corrosion resistance and machining properties. This clad steel plate is layered in either a surface layer region/transition region/inner layer region or a surface layer region/transition region/inner layer region/transition region/surface layer region configuration in the plate thickness direction. The surface layer region extends in the plate thickness direction from the surface to a position where the Cr concentration is 95% of the Cr concentration at the surface. The transition region extends in the plate thickness direction from a position adjacent to the surface layer region to a position where the Cr concentration is 13.0% by mass or higher. The inner layer region is adjacent to the transition region. The width of the transition region is at least 5 μm on average. The average thickness of the surface layer region is at least 5% of the total thickness of the steel plate but less than the thickness of the inner layer region. The degree of integration of the αFe phase of the inner layer region in the (222) plane is 60-100% (inclusive).
