Q345 Steel Properties and Introduction. 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 gradesQ345A, Q345B, Q345C, Q345D and Q345E. Q345 steel has good weldability, cold & hot workability and corrosion

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. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20 21 percent of its initial length.

Yield strength of Q345B is 345 Mega Pascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20 21 percent of its initial length. Tensile strength

For example, Q345B hot rolled steel plate, Q345B hot rolled steel coil/sheet. Material Q345B has comprehensive mechanical and welding property. As it shows good performance in structural purposes, material Q345B is widely used as welding structural part in manufacturing of ship, railway and vehicles, bridges, boiler,etc.

Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20 21 percent of its initial length. Density, Thickness and Mass 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 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

Q355 Steel Introduction. Q355 steel is a new Chinese steel grade of 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 levelsQ355B, Q355C and Q355D.. Q is the first letter of Chinese Pinyinqu fu dian, which means Yield Strength, 355 is the minimum value of yield strength 355

Q345 steel specificationQ345 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

Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20 21 percent of its initial length. Density, Thickness and Mass 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.

For example, Q345B hot rolled steel plate, Q345B hot rolled steel coil/sheet. Material Q345B has comprehensive mechanical and welding property. As it shows good performance in structural purposes, material Q345B is widely used as welding structural part in manufacturing of ship, railway and vehicles, bridges, boiler,etc.

Q345 is a low alloy steel widely used in Bridges, vehicles, ships, construction, pressure vessels, special equipment, etc. Q means yield strength and 345 means yield strength of this steel is 345MPa.Of the low alloy materials, Q345 is the most common.

Elongation for Q345 is at the bottom end of the specification which is 0.22% while the local manufactured tube is an average is 0.37%. Lastly but importantly the minimum yield of Q345 is 345MPa which is not the same as the minimum yield of grade S355 which is 355MPa. (For thicknesses less than 16mm)
