    Technology

  • SMA400AW SMA400BW SMA400CW weathering steel plate
  • Yusheng steel
  • Under Japanese steel specification JIS G3114,there are hot rolled atmospheric corrosion resisting steel plate SMA400AW,SMA400BW,SMA400CW and other weathering steel grades with different mechanical strength and chemicals.The letter symbol W denotes that the plates are usually used in the delivered condition or chemically treated against rusting,steel class AW,BW,CW named according to different impacting test temperature and energy.For atmospheric corrosion resistance steel plate SMA400AW,these plates do not need to be down low temperature impacting test in standard,for weathering steel plate SMA400BW,low temperature should be under zero centigree with minimum 27 J,and for weathering resistance steel plate SMA400CW,impacting test shall be down under zero centigree with minimum energy value at 47 J.And the impacting test is applied only to the steel plates exceeding 12 mm in thickness.

     

    Weathering steel plate SMA400AW,SMA400BW,SMA400CW particularly imparted with a high weldability to be used for briges,building and other structures.In accordance with the agreement between the purchaser and the supplier,weld cracking susceptibility of material may be applied instead of carbon equivalent.
