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 increases.
Q345R Boiler & pressure vessel steel plates,also named as pressure vessel steel plates which including carbon steel and alloy steel for High or intermediate and low temperature services.
