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 plate decreases as plate thickness Q345 Steel, Q345A Q345B Q345C Q345D Q345E Equivalent Dec 08, 2019 · Q is the first letter of Chinese Pinyin:qu fu dian, that means Yield Point, 345 is the minimum value of yield strength 345 MPa for steel thickness 16mm. Datasheet and Specification. Datasheet and specification are listed in the tables below,
Q345B 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 Q345B/16Mn seamless steel pipe Hebei Haihao GroupQ345B seamless steel pipe used to be called:16Mn seamless steel pipe. Q345 seamless steel pipe is a kind of steel pipe material. Q is the yield of this material,and then 345 means the yield of this material is around 345. As the thickness of the material increases,the yield value will decrease.
