2.0*355 (Q345B) Steel Strip Rolled Successfully

On November 29, the factory successfully rolled the newly developed Q345B steel grade and 2.0*355 (Q345B) steel strip specification for the first time. Q345B steel grade is a low-alloy high-strength structural steel that implements the regulations of GB/T1591-2008. This product contains less phosphorus and sulfur. It makes that more difficult to smelt. 2.0*355 (Q345B) steel strip is characterized by thin thickness, hard material, and high strength, so it is hard to mass-produce such products. However, the factory can ensure the stable operation of mass production after sufficient preparation in the early stage and strictly following the process requirements.
