A brief introduction to Chinese GB standard - IMRI Steel

Mar 17, 2020 · Q345 steel, with charicteristics of 7.85 g/cm3 material density, and 470-630 Mpa tensile strength, is a Chinese GB standard low alloy high strength structural steel. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Point, 345 is the minimum value of yield strength for steel thickness less than 16mm. It is commonly used material among low alloy materials Carbon Steel Plate - Buy Product on q345b,q345c,q345d,q345e,q390,q390b,q390c,q390d,q390e,q420,q420b,q420c,q420d, q420e,q460,q460d,q500c,q500d,q500e,q550c,q550d,q550e,q620c,q620d,q620e,q690a,

Analyzing the Q345D channel steel residual stress by

Sep 18, 2018 · When the wall thickness of Q345D channel steel reaches a certain degree, not only the transverse residual stress value near the weld zone is converted into compressive stress, but also the peak value of longitudinal residual stress at weld toe can be significantly reduced, and the greater the wall thickness of Q345D channel steel is. The decrease of longitudinal residual strain peak is greater.
