STAINLESS STEEL-CLAD STEEL PLATE HAVING EXCEPTIONAL CORROSION RESISTANCE TO SEAWATER

摘要

Seawater corrosion resistance to meet the corrosion resistance and mechanical properties at the same time provides excellent stainless steel clad sheet. Abutting material of the stainless steel clad sheet, in mass%, C: 0.030% or less, Si: 0.02~1.50%, Mn: 0.02~2.0%, P: less than 0.040%, S: less than 0.030%, Ni: 22.0~25.0%, Cr: 22.0~26.0%, Mo: 3.5~5.0%, N: 0.10 to 0.25%, and containing, the balance being substantially Fe and inevitable impurities is made of, in addition, satisfy the following relation (1), and the precipitated state in the steel present, Cr is 0.3% or less, an excellent sea water corrosion resistance in stainless steel clad sheet, characterized in that Mo is 0.2% by mass or less in. Cr + 3.3Mo + 16N 40 (1). In addition, each element symbol represents the mass% of each element.
