Dec 12, 2019 · The chemical element is similar to 16Mn, and Q345 increases the micro-alloy element V, Ti and Nb which refines the grain, greatly improving the toughness and comprehensive mechanical properties of steel, thus allows a greater thickness.
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;
Answer:Their differences can be found in mechanical properties and chemical composition. Mechanical Properties:Steel. W.T(mm) Q345B Low Alloy Galvanized Steel Square Pipes for Contructural Projects. Non Alloy Steel Structural Hollow Section EN10210.
GB/T1591 GB/T3274 Q345B low alloy high strength steel Q345B low alloy high strength steel plates have 2 standards at present:GB/T1591 and GB/T3274. GB/T3274 is new version based on GB/T1591, but a lot of mills still conduct GB/T1591 at present. Q345B low alloy high strength steel plates enjoy good comprehensive performance, low temperature performance, cold stamping performance, good weldability and machinability.
GB/T1591 Q345B hot rolled high - steel-plate-chinaQ345B 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. GB/T1591 Q345B steel plates physical properties:Annealing hardness:235HBS. Cold pull hardness:262HBS. Preheating temperature:522°C. Quenching temperature:salt-bath furnace:1191°C.
