S420NL Steel plate
S420NL steel is a good weldability structural steel grade. General requirements for arc welding of the steels specified shall be as given in EN 1011-2.
Compare the S355N, S420NL steel grade has more yield and tensile strength. The equal grade of S420NL is S420ML.
Gnee steel has much experience in manufacture S420NL. we cooperated with wuyang mill of HBIS to produce the max thickness 300mm in electroslag remelting technical. Our advantage is that we could supply goods in the fastest delivery time, even in one plate in usual specification.
