S355J2WP steel plate is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.
S355J2WP Weathering resistance steel plate under EN10025-5 shall be done impacting test at minus twenty centi degree with the minimum energy 27 J.Comparing with steel plate S355J0WP which shall be at zero centi degree.S355J2WP steel has the barrier layer owning to the chemical contents,the formation of this layer can keep approx. four years and prevent water,oxygen and sulphur dioxide from contacting the surface of S355J2WP steel plate.
