This part of ISO 630 specifies the technical delivery requirements for hot-finished hollow sections of circular, square or rectangular form. It is applicable to hollow sections formed hot with or without subsequent heat treatment or formed cold with subsequent heat treatment to obtain equivalent metallurgical conditions to those obtained in the hot-formed product. Fine grain steels are generally delivered in the normalised condition.
The grades, chemical composition and mechanical properties for non-alloy steels and fine grain steels are given in annexes A and B, respectively.
NOTE 1 Requirements for tolerances, dimensions and sectional properties are given in ISO 657-14.
NOTE 2 For the technical delivery requirements of hot rolled structural steels in other product forms, e.g. plates, wide strip, flats, bars and other structural sections, see ISO 630:1995.
NOTE 3 For cold-formed structural hollow sections, see ISO 10799.
