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 A572GR50 Q345B S355JR Low Alloy Hot Rolled Steel Plate SAE1006 / SAE1008 HRC Hot Rolled Coil Low Carbon Steel Large Stock.
