EN 10025-5 S355J0WP Weather Resistant Steel Plate

S355J0WP weather resistant steel plate is a structural weathering steel, also known as atmospheric corrosion-resistant steel. Its primary alloying elements are chromium, nickel, and copper, with phosphorus added to impart exceptional self-protection properties.

When the steel reacts with atmospheric elements, a dense, stable rust layer forms on the surface over time, effectively preventing further corrosion.

Regarding mechanical properties, the yield strength of S355J0WP hot rolled weather resistant steel plate varies with thickness: no less than 355 MPa for thicknesses up to 16 mm, 345 MPa for 16–40 mm, and 335 MPa for 40–63 mm. Its tensile strength ranges from 470 to 630 MPa, with elongation exceeding 20%.

It can withstand an impact of 27 joules at 0°C, ensuring excellent toughness and reliability.

Chemically, the steel contains 0.40–0.80% chromium, 0.25–0.55% copper, nickel not exceeding 0.65%, and phosphorus between 0.035–0.12%. These elements collectively impart exceptional weather resistance to the material.

S355J0WP high stregth weather resistant steel plate offers not only outstanding strength and corrosion resistance but also an aesthetically pleasing surface finish.

This makes it a durable and economical solution for architectural applications such as steel bridges, chimney exhaust systems, exterior cladding, and steel sculptures.

S355J0WP corten steel plate offers a durable and economical structural steel solution for steel bridges, chimney gas applications, and steel sculpture architecture, thanks to its aesthetically pleasing surface finish.

Furthermore, this steel with enhanced atmospheric corrosion resistance has a wide range of applications: covering building structures, chimneys, metal products, freight cars, silos, towers, and more.

Its suitability for these applications stems from their prolonged exposure to harsh environments like wind, rain, humidity, salt spray, or flue gases.

While ordinary steel rapidly corrodes and loses strength under such conditions, S355J0WP high strength low alloy corten steel plate develops a dense, stable protective rust layer on its surface.

This layer effectively resists corrosion, extends service life, and reduces frequent maintenance costs. Simultaneously, it delivers a distinctive natural aesthetic appeal in architectural and landscape applications.
