With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
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. According to GB/T 1591 2008, Q345 material has 5 quality grades: Q345A, Q345B, Q345C, Q345D and Q345E.
The ASTM equivalent of Q345B is A572 gr.50. This is a steel plate that is used in the construction of large structures like bridges.
Q345 steel specification and equivalent standard Q235 carbon structural steel is made for metal construction that doesnt have high demand for steel strength, tie rod, connecting rod, hook, coupler,equivalent of q345b Q345 is low alloy structural steel with good mechanical properties, low temperature performance, equivalent of q345b
A yield strength or yield point is the material property defined as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed, Yield strength of Q345B is 345 MegaPascals.
The density of Q345B steel is approximately 7.8 (where water is 1.0), and it is commonly available in thicknesses ranging from 2 mm to 12.7 mm (12.7 mm is approximately half-inch thick plates), with sheets typically sold in 1 to 1.35 meter wide splits.
Q345 steel equivalent is standard Grade Q345 Imported Tube does not conform to grade S355 It has come to the attention of the ASTPM that Grade Q345, a standard in China, Grade Q345 it is not equivalent to S355 in terms of mechanical properties in Q345 Steel Equivalent - Alibaba

Q345 Structural Steel Equivalent ASTM A572 Grade 50 Posted:2015-11-30 03:16:23 Q345 structural steel has good mechanical properties, low temperature performance, plasticity and good weld ability, Q345 steel is mostly used in low pressure vessel, oil tank, vehicles, cranes, mining machinery, power stations, mechanical parts, building structure equivalent of q345b
Q345 steel is one kind of Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, used for a number of manufacturing purposes. To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572.
Xinsteel can offer steel coils,steel plates,angles,channels for Q345B materials.The equivalent steel grade with Q345B are EN 10025-2 S355JR,ASTM A572/A572 A572 Grade 50 and DIN 17100 St52-3. +86 371 55057610
The imported product is a Carbon Manganese steel while locally produced tube is typically produced with low Carbon micro-alloyed steel. Thus the Q345 has a much higher Carbon Equivalent content close to the maximum recommended maximum value of 0.45.
