A brief introduction to Chinese GB standard - IMRI SteelMar 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.
Chemical Composition of Structural Steels carbon is by far the most important chemical element in steel. Increasing the carbon content produces a material with higher strength and lower ductility. Structural steels, therefore, have carbon contents between 0.15 to 0.30 percent; if the carbon Typical amounts of molybdenum are 0.08 to 0.25

GB/T1591 Q345B hot rolled high - steel-plate-chinaGB/T1591 Q345B hot rolled high strength low alloy structural steel plates are 'general purpose' manufacturing steel plates, used for sheet metal, light structural elements of household goods, and similar uses where it won't be used as a major structural component.
Q345 Carbon Mild Steel Q345A Q345B Q345C Q345D Q345E Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa, it has better properties than Q235. According to GB/T 1591 2008, Q345 material has 5 quality grades:Q345A, Q345B, Q345C, Q345D and Q345E.
Q355 steel is a Chinese low alloy high strength structural steel, which replaced Q345, the material density is 7.85 g/cm3. According to GB/T 1591 -2018, Q355 has 3 quality levels:Q355B, Q355C and Q355D. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355 MPa for steel thickness 16mm, and tensile strength is 470-630

Structural Steel - S235, S275, S355 Chemical Composition May 11, 2012 · The Chemical composition of Structural Steel is extremely important and highly regulated. It is a fundamental factor which defines the Mechanical properties of the steel material. In the following table you can see the Max % levels of certain regulated elements present in European Structural steel grades S235, S275 and S355.
Q345B steel is a Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, and is used for a number of manufacturing purposes. It is a steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities (mostly sulfur, chromium and nickel).
