It has excellent weldability! A steel plate improved based on rolled steel plates for architectural structures.
"SN Steel Plate" is a type of steel material established based on JIS G 3136, which satisfies the specific performance requirements of steel frame structures. It utilizes a unique manufacturing process that incorporates an electric furnace, external refining, and a four-stage thick plate rolling mill, with further improvements made to the steel plate. Due to its component design that keeps the carbon equivalent and susceptibility to welding cracks low, it has excellent weldability and is easy to manage during construction. 【Features】 ■ Extremely excellent weldability ■ High toughness is ensured ■ Superior characteristics in the thickness direction ■ Low yield ratio ■ No acoustic anisotropy For more details, please refer to the catalog or feel free to contact us.
