Atmospheric Corrosion Resistant Steel Plates for Sea side area
In addition to conventional atmospheric corrosion resistant steels, JFE Steel has developed corrosion resistant steels for sea side areas, where ordinary atmospheric corrosion resistant steel is not practical without painting, because of salty exposure.These steels are the standard type(Type1),which includes 1.5%Ni-Mo, and higher resistant type(Type2) including 2.5%Ni. For the purposes of preventing stain by watery rust at the initiation of exposure in atmospheric environment, JFE markets the rust stability accelerating paint "CUPTEN COAT M" and "e-RUS".
