What is EN 10025-5 S355J2W steel plate?
S355J2W grade steel under EN 10025-5 standard is a weathering resistant steel, which could be more accurately be termed as an "Atmospheric Corrosion Resistant Steel".
S355J2W steel plate is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels. Its chemical composition promotes the early formation of an adhering protective layer of rust when exposed to the elements.
Corten EN 10025-5 S355J2W steel plates are weathering steels commonly used for outdoor structures. These steels have a higher resistance to atmospheric corrosion than typical mild steels. Often, welds on these steels are specified for similar corrosion resistance and color match.
Standard of EN 10025-5 S355J2W steel plate
EN 10025-5: European standard for hot-rolled structural steel. Part 5 - Technical delivery conditions for structural steels with improved atmospheric corrosion resistance

Names of EN 10025-5 S355J2W steel plate
S355J2W steel, S355J2W steel sheet, S355J2W corten steel plate, S355J2W weathering steel plate, S355J2W weatherproof steel plate, S355J2W weather resistant steel plate, S355J2W atmosphere corrosion resistant steel plate, S355J2W anti corrosion steel plate, etc.
The steel category of EN 10025-5 S355J2W steel plate
EN 10025-5 S355J2W steel belongs to corten steel/ whethering steel.
Corten steel is a high strength weathering steel. The word "CorTen" is the trademark name given to a weathering steel alloy material originally produced by United States Steel.
Corten steel alloy falls into the category of those that were developed to reduce or eliminate the use of coats, primers or paints on the material to make it rustproof. When exposed to the environment, corten steel forms an outer rust layer that protects this steel from corrosion. This is the reason why corten steel is also called weathering steel.

Features of EN 10025-5 S355J2W steel plate
EN 10025-5 S355J2W steel plates are having a higher level of corrosion resistance due to oxidation, reduction, toxic gases, and reactive chemicals. They can also resist a larger amount of heat and higher temperature and can be easily welded and machined. EN 10025-5 S355J2W plates are having greater toughness and hardness and thus are durable for the longest time. These plates are having much ductility and thus can be designed in various dimensions with different levels of thickness. EN 10025-5 S355J2W sheets are also suitable for working in a very changing and hostile environment and can be used in the bare condition. The alloy is the weathering bridge structural steel alloy. S355J2W steel is a good weathering steel plate which can be used in varying weather condition. These S355J2W steel plates are being delivered in different conditions as the hot rolled, normalized, cold rolled, tempering and quenching, the thermal mechanical control process, and the electroslag remelting technical condition.
S355J2W steel plate is available in a wider variety of shapes, thickness, and dimensions.
