This standard was developed in accordance with the rules specified in GB/T 1.1-2009.
This standard combines "Hot-rolled Quality Carbon Structural Steel Sheets and Strips" (GB/T 710-2008) and "Hot-rolled Quality Carbon Structural Steel Plates Sheets and Wide Strips" (GB/T 711-2008) by amendment.
This standard replaces "Hot-rolled Quality Carbon Structural Steel Sheets and Strips" (GB/T 710-2008) and "Hot-rolled Quality Carbon Structural Steel Plates Sheets and Wide Strips" (GB/T 711-2008). Compared with GB/T 710-2008 and GB/T 711-2008, the major technical differences in this standard are as follows:
——Cancel relevant designations of rimmed steel;
——Cancel the grade of pulling edge;
Add designations 35Mn, 55Mn and 70Mn (see Table1, Table 2 and Table 3);
——Tighten control of harmful element sulfur in steel (see Table 1);
——Adjust delivery conditions of some designations (see Table 2).
This standard was proposed by China Iron & Steel Association.
This standard is under the jurisdiction of the National Technical Committee 183 on Iron and Steel of Standardization Administration of China (SAC/TC 183).
The previous editions replaced by this standard are as follows:
