S355J0W High Strength Low Alloy Weathering Steel Plate

S355J0W High Strength Low Alloy Weathering Steel Plate, which belongs to the weathering steel under the European standard (EN 10025-5:2004), also known as atmospheric corrosion resistant steel.

This kind of steel adds a small amount of corrosion resistant elements such as copper and nickel on the basis of ordinary steel to improve its corrosion resistance in atmospheric environment.

Exceptional weather resistance and corrosion resistance: S355J0W steel plates maintains long-term stable performance in outdoor environments without requiring additional coatings or anti-corrosion treatments, significantly reducing maintenance costs.

Its atmospheric corrosion resistance is 2–8 times that of ordinary carbon steel, and it can still form a dense, stable protective rust layer in humid, rainy, or industrially polluted atmospheres.

High Strength Characteristics: The minimum yield strength of this steel is no less than 355 MPa for thickness ≤16 mm, 345 MPa for 16–40 mm, and 335 MPa for 40–63 mm.

Its tensile strength ranges from 470–630 MPa, meeting diverse complex engineering requirements.

Excellent weldability and workability: S355J0W hot rolled steel sheet facilitates easy cutting, bending, welding, and other processing operations during manufacturing.

With an elongation of no less than 20%, it offers greater design flexibility for engineers and manufacturers.

Superior impact toughness: In 0°C impact tests, S355J0W Weather Resistant Steel Plates delivers impact energy of no less than 31 J, demonstrating excellent impact resistance and withstanding significant impact loads even in low-temperature environments.

Energy-saving and consumption-reducing advantages: Leveraging its superior weather resistance and strength properties, S355J0W reduces protective coating and maintenance costs by approximately 25–30%. Additionally, it enables 10–20% thinner steel sections in structural designs, effectively lowering material consumption while conserving labor and energy resources. This results in more competitive overall project costs.

S355J0W steel plates is suitable for various welded, bolted, and riveted structures, such as steel frame structures, bridges, storage tanks and vessels, exhaust systems, vehicles, and equipment construction.
