Abstract

The hardened steel tube member is formed from a zinc -coated steel tube. The cross -section , which is perpendicular to the longitudinal direction , at the center of the longitudinal direction of the GI- zinc coated steel tube is substantially a V -shape , the V -shape comprising a contacting section in which the inner surfaces of the GI -zinc coated steel tube contact each other. The contacting section is integrated by a Fe- Zn alloy phase. The micro Vickers hardness at a depth of 50 µm from the surface layer of the base metal is 95% or more of the micro Vickers hardness at a depth of 200 µm from the surface layer of the base metal.
