されてきた。Conventionally, materials for the ice chambers and chemical tanks of strawberry water condensation equipment, as well as materials for parts exposed to highly corrosive liquids such as seawater, phosphoric acid, and flowing acid, have been used on the side exposed to these liquids. Clad steel plates made of corrosion-resistant copper, copper alloys, or stainless steel have been used as surface materials.

あった。Figure 1 shows conventional stainless clad steel. There are 4 scratches (4) on S'US504 stainless steel 2 with a thickness of 2 cm.
(including cracks, pitting corrosion, etc.), and when a part of the carbon steel 1 is exposed to a highly corrosive liquid 5 such as seawater (for example, seawater), the carbon steel 1 is damaged due to the battery action between the stainless steel 2 and the carbon steel 10. Corrosion of 1 is accelerated, resulting in large corrosion holes 6.
In the case of conventional clad steel sheets, scratches 4, cracks, or corrosion (for example, pitting corrosion) occur in a part of the surface material 2 made of copper, copper alloy, stainless steel, etc., and the carbon steel 1 which is the base material When exposed, the corrosion of the carbon network 1, which is the base material, is significantly accelerated due to the battery action between it and the surface material 2.

ラツド鋼板を提供するものである。The present invention is a copper, copper alloy, or stainless steel clad face plate in which scratches, cracks, corrosion, etc. occur on a part of the surface material of the copper, copper alloy, or stainless steel, and the carbon steel that is the base material is corroded by seawater. The present invention provides a multi-clad steel plate that can prevent corrosion of carbon steel, which is a base material, even when exposed to strong liquids.

面材の一部に傷、割れあるいは腐食などが起こり。That is, the present invention uses surface materials such as copper, copper alloy plates, and stainless steel plates, and carbon steel plates, which have lower natural electrode potentials in solutions such as seawater than carbon steels such as zinc, aluminum, or their alloys. Cladding with thin plates of base metals may cause scratches, cracks, or corrosion on some surface materials such as copper, copper alloys, or stainless steel.
