Abstract
Provided is an electric-resistance-welded steel pipe or tube for a hollow stabilizer where the formation of not only a ferrite decarburized layer but also a total decarburization layer can be suppressed even when heat treatment is performed in the air. The electric-resistance-welded steel pipe or tube for a hollow stabilizer has a predetermined chemical composition, and the depths of total decarburized layers on an inner surface and on an outer surface are 100 μm or less.
