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 China Q345b Steel, Q345b Steel Manufacturers, Suppliers China Q345b Steel manufacturers - Select 2021 high quality Q345b Steel products in best price from certified Chinese Steel Structure, Steel Wire suppliers, wholesalers and factory on Made-in-China

treatment, and Micro structure, etc. It also contains the use of Q345,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application. Datasheet for Steel Grades Structure Steel Q345 Q345 Standard Number:ITEM Standard Number Descriptions Q345 Chemical composition(mass fraction)(wt.%) Differences in mechanical properties of Q345B and Q355B Q355B steel is a upgraded low alloy steel of grade Q345B. There are some differences between Q345B and Q355B steel. Q345B steel and Q355B steel differences in mechanical properties. Q345B steel mechanical properties:Yield Strength requirement in different thickness:t16mm:345MPa; 16-40mm:335MPa; 40-63mm:325MPa; 63-80mm:315MPa; GB/T1591 Q345B carbon and low alloy steel - BEBON steelBBN steel offer GB/T1591 Q345B carbon and low alloy steel in China. Q345B material is low alloy structural steel with good mechanical properties, low temperature performance, plasticity and good weldability, it is mostly used in low pressure vessel, oil tank, vehicles, cranes, mining machinery, power stations, mechanical parts, building structure, general metal parts, Q345(E) steel plate is

Q345 steel specification:Q345 steel belongs to 16Mn steel grade, usually it is produced in hot rolled state, hot rolled steel plate, hot rolled steel coil/sheet, it has comprehensive mechanical and welding property, as it shows good performance in structural purposes, it is widely used as welding structural part in manufacturing of ship, railway and vehicles, bridges, boiler, pressure vessel container, steel oil tank, etc. Yield point of Q345 steel Q345 Steel Specification and Equivalent StandardQ345 steel specification:Q345 steel belongs to 16Mn steel grade, usually it is produced in hot rolled state, hot rolled steel plate, hot rolled steel coil/sheet, it has comprehensive mechanical and welding property, as it shows good performance in structural purposes, it is widely used as welding structural part in manufacturing of ship, railway and vehicles, bridges, boiler, pressure vessel Q345B steel vs Q355B steel - Bebon SteelQ345B steel vs Q355B steel. Q355B is a new type of Q345B steel under GB/T1591-2018 low alloy structural steel standard. It is equivalent to Q345B in GB/T1591-2008 version and S355JR in EN 10025-2:2004 version. Chemical composition (%) comparison of Q345B and Q355B. Material.

Q355B material chemical composition - Bebon Steel

Q355B material chemical composition. Q355B material is a low-alloy high-strength structural steel, where "Q" means yield strength, 355 means that the yield strength of this steel is 355MPa, and its yield value will decrease as the thickness of the material increases. Q355B steel plate is widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment, etc. What is material Q345B equivalent ASTM steel - BEBON STEELWhat is material Q345B equivalent ASTM steel? To some extent, the material Q345B possesses the same property and composition of ASTM A572 Gr 50 steel, namely the material Q345B equivalent ASTM steel is A572 Gr 50.
