A brief introduction to Chinese GB standard - IMRI Steel

Mar 17, 2020 · Defination of Q345. 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 Boiler Alloy Steel Sheet Plate - Quality Boiler Steel Tube 1.Low alloy high strength structural steel Plate A345A Q345B Q345C Q345D Q345E Q390A Material A345A Q345B Q345C Q345D Q345E Q390A Thickness 8mm-800mm Width 1500mm-4200mm Length 6000mm-18000mm Delivery condition
