Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009 "Guidelines for Standardization Work Part 1. Structure and Compilation of Standards". This standard was prepared with reference to IEC 60404-8-5. 1989. This standard replaces Q/BQB 484-2018. Compared with Q/BQB 484-2018, the main amendments to this standard are as follows. -Supplemented the national reference documents related to the ingredients; -Added information required for ordering; -Added B550TF179 grade and its corresponding technical requirements; -Adjusted the lower limit of supply thickness in Table 2, from 0.8mm to 0.7mm; -Supplemented the chemical composition control requirements in Table 3; -Added Appendix A brand approximate comparison table. Appendix A of this standard is an informative appendix. This standard is proposed by the Manufacturing Management Department of Baoshan Iron and Steel Co., Ltd.
