Weathering steel plate SMA490AW,SMA490BW,SMA490CW are the hot rolled atmospheric resisting steels particularly imparted with a high weldability to be used for marine containers for shipping,main body of large briges and high buildings.Weathering steel plate SMA490AW,SMA490BW,SMA490CW owned minimum yield strength for the plates thickness equal and under 16mm is 365 Mpa,and 355 Mpa for plates thickness from 16 to 40mm,335 Mpa for steel plate thickness between 40mm and 75mm,325 Mpa for plates thickness from 75 to 100mm.For all the thickness of steel plate SMA490AW,SMA490BW and SMA490CW, the tensile strength shall be 490-610 Mpa.

Now in southeast countries,more and more steel container manufacturers are choosing the steel grade SMA490AW,SMA490BW and SMA490CW as their steel materials instead of SS400 steel. Its main reason is weathering steel plate and sheet SMA490AW,SMA490BW and SMA490CW exhibit increased resistance to atmospheric corrosion compared to other steels. This is because the steel forms a protective layer on its surface under the influence of the weather due to their chemical composition.
