ASTM A1008/A1008M-21a 冷轧碳素结构钢薄板高强度低合金高强度低合金具有改进的成形性所需硬度固溶硬化和烘烤硬化的高强度低合金的标准规范

1.1 This specification covers cold-rolled, carbon, structural, high-strength low-alloy, high-strength low-alloy with improved formability, required hardness, full hard, solution hardened, and bake hardenable steel sheet, in coils and cut lengths. 1.2 Cold rolled steel sheet is available in the designations as listed in 4.1. 1.3 This specification does not apply to steel strip as described in Specification A109/A109M. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

BS ISO 630-4:2021 结构钢 高屈服强度调质结构钢板和宽扁钢板交货技术条件

What is ISO 630 ‑ 4 about?    ISO 630-4 is the fourth part in the multi-series of International Standards on ‘Steels for structural purposes’. ISO 630 ‑ 4 specifies qualities for high-yield-strength quenched and tempered structural steels. ISO 630 ‑ 4 applies to steel plates and wide flats rolled on a reversing mill which is used in the quenched and tempered condition and normally intended for welded or bolted structures.   ISO 630

This document specifies requirements for flat and long products of hot-rolled weldable fine- grain structural steels in the as-rolled (for SG grades only), normalized/normalized rolled and thermomechanical processed delivery conditions. It applies to steel plates rolled on a reversing mill, wide flats, hot-rolled sections and bars, which are intended for use in heavily loaded parts of welded or bolted structures. This document covers 13 grades and 6 qualities. Grades S275, S355, S390, S420, S460 and S500 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. The steels specified in this document are applicable to hot-rolled plates, wide flats, sections and bars with a minimum nominal thickness of 3 mm and a maximum nominal thickness of 250 mm for grades S275N, S355N, S390N, S420N and S460N, a maximum nominal thickness of 150 mm for grades S275M, S355M, S390M, S420M, S460M, and S500M, a maximum nominal thickness of 200 mm for grades SG245, SG325 and SG415, a maximum nominal thickness of 100 mm for grades SG345, SG365 and SG460, and a maximum nominal thickness of 40 mm for grade SG290.
