EN 10025-5 S355J0W Corten steel plates are premium structural steels enriched with chromium, nickel, and copper alloy elements, alongside a controlled addition of phosphorous. This unique chemical composition grants S355J0W its legendary self-protection capability.
S355J0W Corten steel weathering steel plates
At Gnee Steel, we specialize in providing high-performance S355J0W steel solutions that meet the most demanding engineering requirements.
What Makes S355J0W Steel Special?
When exposed to atmospheric elements, EN 10025-5 S355J0W weathering steel develops a dense, stable protective oxide layer (patina). This layer acts as a barrier that prevents further oxidation of the underlying steel.
Key Benefits:
- Cost-Effective: Eliminates the need for initial painting and ongoing maintenance treatment.
- Durability: Superior resistance to atmospheric corrosion compared to standard carbon steel.
- Aesthetic Appeal: Develops a unique, industrial "rust-like" appearance favored by modern architects.

What is the American equivalent of S355J0?
ASTM A572 Grade 50: This is a common equivalent to S355J0 in terms of mechanical properties and usage in construction and structural applications. ASTM A36: While A36 has lower mechanical properties than S355J0, it can sometimes be used as an equivalent in less demanding applications.
What grade of steel is S355J0?
S355J0 is a non-alloy structural steel grade defined by the EN 10025-2 standard. The "S" denotes "structural," indicating its use in constructing buildings, machinery, or infrastructure.
Can S355 be hardened?
S355 is not ideally suited to hardening, though it can be subjected to limited heat treatment process such as case hardening. When hardening S355 heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component.
Can S355 be welded?
S355 structural steel, widely used in offshore, shipbuild- ing, and construction industries, is known for its excellent weld- ability and durability [1], as well as for its corrosion and fatigue characteristics.
