How to weld and repair s355j2+n-z35 steel plate

s355j2+n-z35 steel plate, SN490 steel is one of the most widely used structural steel for building in contemporary society. Because of its special construction method requirements, it improves the "strength", "toughness" and "weldability", and has better shock resistance effect. SN490 steel is different from the earlier SS series and SM series steel. Because there is no provision for the yield strength or tensile strength, the strength of building materials may be too high, the problem of yield ratio and the lack of alloy elements make it difficult to control.
