Title:
Conversion treatment steel pipe
Document Type and Number:
Japanese Patent JP6277168
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a chemically treated steel pipe having weather resistance and adhesion of a chemically treated film and having color change with time suppressed.SOLUTION: A chemically treated steel pipe 100 has a chemically treated film 170 on a plating layer 120 on a steel plate 110. The chemically treated film 170 contains a fluorocarbon resin, a specific base resin other than the fluorocarbon resin, and metal flakes 171. The content of the fluorocarbon resin is 3.0 mass% or more in terms of fluorine atom relative to the total amount of the fluorocarbon resin and the base resin, while the content of the base resin is 10 pts.mass or more relative to 100 pts.mass of the fluorocarbon resin. The content of the metal flakes 171 is 10-60 mass% in the chemically treated film 170.SELECTED DRAWING: Figure 1
