Title:
A manufacturing method of an electric-resistance-welding stainless steel clad steel pipe
Document Type and Number:
Japanese Patent JP6164368
Kind Code:
B2
Abstract:
Provided are an electric-resistance-welded stainless clad steel pipe which has excellent weld characteristics, even without performing an additional welding process that is required in existing techniques after electric resistance welding, and a method of manufacturing the same. An electric-resistance-welded stainless clad steel pipe is manufactured by forming a hot-rolled steel strip of clad steel including low-carbon low-alloy steel and stainless steel into a cylindrical shape, and electric-resistance-welding the edges of the hot-rolled steel strip, characterized in that the flattening characteristic of an electric resistance weld, as-welded, satisfies the following formula: h / D < 0.3 where h is the flattened height at fracture (mm) and D is the outer diameter of the pipe (mm).
