标准范围

This part of ISO 630 specifies qualities for steels with improved atmospheric corrosion resistance forgeneral structural use. It applies to steel plates rolled on a reversing mill, wide flats, hot-rolled sectionsand bars, which are used in the usual delivery conditions as given in 6.3, and normally intended forwelded or bolted structures.This part of ISO 630 covers nine (9) grades and four (4) qualities. Grades S235 and S355 are covered inAnnex A. Grades SG245, SG345, SG365, SG400, SG460, SG500, and SG700 are covered in Annex B. Not allgrades 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, certain of which are covered byother 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”.
