This part of this European Standard specifies technical delivery conditions for hot-finished seamless, electric welded and submerged arc welded steel structural hollow sections for mechanical engineering purposes of circular, square, rectangular or elliptical forms.
It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment above 580 °C to obtain equivalent mechanical properties to those obtained in the hot formed product.
