ISO 630-1-2011 pdf free.Structural steels – Part 1: General technical delivery conditions for hot-rolled products.
This part of ISO 630 specifies the general technical delivery conditions for steel flat and long products (platel sections/wide flats and bars) used principally for general-purpose structural steels. The steels specified in this part of ISO 630 are intended for use in welded or bolted structures.
The specific requirements for structural steels are given in the individual parts of ISO 630.
This part of ISO 630 does not include the following structural steels, some of which are covered by other International Standards:
— sheet and strip: refer to ISO TC 1715C 12 “Continuous mill flat rolled products”;
— tubular products: refer to ISO TC 5/SC 1 “Steel tubes”.
NOTE Lists of standards covered by ISOITC 17/SC 12 and ISOITC 5/SC I are available on the ISO Web site.
