GB/T1591 Q345B Low Alloy High Strength Steel Plate, Coils Dec 10, 2018 · Q345B grade poses great affinity to stand within the corrosive environments. These have good fabricability and workability. It resists pitting and crevice cracking at reducing environments at elevated temperatures. Plates and coils have high sheen and strong finish.
As we all know, China's steel production is the largest variety of rebar, followed by steel plate and sheet, and the largest percent of steel grade produced in the plate is Q235B, followed by Q345B. The biggest impact of the new GB/T 1591-2018 release is Q345B, because the output of other grades has little effect. Q235B Included in 3 standards (China) - MetalDatafoQ235B Included in 3 standards (China) Chemical composition C < 0.22 Si < 0.35 Mn < 1.4 P < 0.045 S < 0.045 Cr < 0.3 Ni < 0.3 Cu < 0.3 N < 0.008 As < 0.08 Fe Rest It's allowed to exceed N content up to 0.014% in finished products.
