Jul 22, 2019 · The lower limit of yield strength of Q235 is 235Mpa, and that of Q345 is 345Mpa (Q means qu in Chinese, and the following value represents the lower limit of yield strength). They have different gold content:Q235 is ordinary carbon steel, Q345 is low alloy steel. Mechanical properties of Q345:Mechanical properties of Q345D seamless pipe: New China Standard-Q345B Changed to Q355BAs 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. According to what we said
