|Publication Date:||1 June 2012|
|ICS Code (Iron and steel products in general):||77.140.01|
This part of ISO 630 specifies requirements for flat and long
products of hot-rolled weldable fine-grain structural steels in the
as-rolled (for SG grades only), normalized/normalize
This part of ISO 630 covers 11 grades and four qualities. Grades S275, S355, S420 and S460 are covered in Annex A. Grades SG245, SG290, SG325, SG345, SG365, SG415 and SG460 are covered in Annex B. Not all grades are available in all qualities, and some qualities have Charpy V-notch requirements.
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 17/SC 12, Continuous mill flat rolled products;
- Tubular products - refer to ISO TC 5/SC 1, Steel tubes.
NOTE Lists of standards covered by ISO/TC 17/SC 12 and ISO/TC 5/SC 1 are available on the ISO Web site.
