Product Description

S355JR St52-3/1.1170 En14/150m19 Carbon Steel Flat Plate Steel

1: Q355 steel introduction
    Q355 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 Q355 steel plate decreases as plate thickness increases.
