Production process of EN 10155 S355J2G1W weathering steel plate

EN 10155 S355J2G1W weathering steel plate is made by adding phosphorus, nickel, copper and other trace elements to the ordinary steel plate in the smelting process. Dense and highly protective film is formed on the steel surface, which hinders the further diffusion of corrosion, so as to protect the following materials to slow down the corrosion.

The appearance of EN 10155 S355J2G1W weathering steel plate is exposed and it can resist corrosion without using other coatings. It is environmental protection, because it has no pollution to the surrounding environment.

EN 10155 S355J2G1W weathering steel plate production process: weathering steel is generally smelted into the furnace, including converter, EAF microalloying, argon blowing refining, low overheat continuous casting, rare earth wire feeding, controlled rolling and controlled cooling. During the smelting process, scrap is added into the furnace together with the charge, and the EN 10155 S355J2G1W weathering steel plate is melted according to the conventional method.

After the steel is discharged, Deoxidizer and alloy are added. After blowing argon into molten steel, the steel is cast immediately. Due to the addition of rare earth elements to EN 10155 S355J2G1W weathering steel plate, the weathered steel is purified, and the inclusion content of EN 10155 S355J2G1W weathering steel plate is greatly reduced.
