Q345 Steel Specification and Equivalent Standard

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 Q345 Steel, Q345A Q345B Q345C Q345D Q345E Equivalent Dec 08, 2019 · Q345 Steel Properties. 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. Q345 steel has good weldability, cold & hot

Q345 steel property and specification are equivalent to

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 Mega Pascals. Q345B straight seam welded steel pipe - Articles FactoryMar 29, 2016 · In the impact of different temperature, impact value is also different. Q345A, Q345B, Q345C Q345D, Q345E.
