CLADDING MATERIAL FOR STAINLESS STEEL CLAD STEEL PLATE STAINLESS STEEL CLAD STEEL PLATE INCLUDING THE SAME AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to a stainless steel clad steel material excellent in corrosion resistance against seawater which maintains both the reliability of the bonded interface and the performance (corrosion resistance and mechanical properties) of the base material and the base material, and a stainless steel clad steel using the stainless steel clad steel. And the like. % Of Si, not more than 2.0%, P of not more than 0.04%, S of not more than 0.03%, Ni of 22.0 to 25.0%, Ni of not more than 0.03%, C of not more than 0.03%, Si of not more than 1.5% The steel sheet according to any one of claims 1 to 3, wherein the steel sheet contains 21.0 to 25.0% of Cr, 2.0 to 5.0% of Mo, 0.15 to 0.25% of N, Fe of unavoidable impurities and inevitable impurities and has an official formation threshold temperature (CPT) , And the corrosion amount of the welded portion of the above-mentioned alloy by the corrosion test specified in NORSOK STANDARD is not more than 1.0 g / m 2, and a stainless steel clad steel sheet using the stainless steel clad steel sheet.
