H series (high-strength steel pipe)
It is best for uses that require steel-pipe strength. It is used for car headrests stays, hammer handles, crowbars, and other products. Weight can be reduced while keeping strength, and the series can be produced to a tensile strength of about 1,000 (N/mm2). Depending on the material, the surface shine and workability can be increased.
