Products Description
S355J2WP Weathering Steel Plateis a fine-grained steel, an alloy structural steel specifically designed for primary forging processes, with properties primarily suited for hot working conditions.
This material carries the EN designation 1.8946 and the chemical composition designation S355J2WP Hot Rolled Weathering Steel Plate.
As an improved atmospheric corrosion-resistant structural steel, S355J2W plates are extensively used in high-speed railway bogies, welded components, bolted assemblies, and riveted structures.
Regarding mechanical properties, S355J2WP High Strength Weathering Steel Plate exhibits a minimum yield strength of no less than 355 MPa for thicknesses ≤16 mm, 345 MPa for 16–40 mm, and 335 MPa for thicknesses between 40–63 mm.
Its tensile strength ranges from 470–630 MPa, with an elongation of no less than 20%. It maintains an impact energy of no less than 27 J at -20°C, demonstrating excellent toughness and reliability.
Regarding corrosion resistance, S355J2WP Corten Steel Plate exhibits outstanding atmospheric weathering performance at ambient temperatures, withstanding corrosion in humid and rainy climates, environments with periodic wet-dry cycles, salt spray, and industrially polluted atmospheres.
Over time, its surface develops a dense, stable protective oxide layer that effectively delays corrosion, significantly reduces maintenance requirements, and extends service life.
Additionally, S355J2WP Hot Rolled Corten Steel Plate exhibits moderately high electrical conductivity and moderately high internal energy, coupled with moderate tensile strength.
This combination of properties makes it particularly well-suited for structures requiring long-term exposure to complex climatic conditions.

Applications Industry
Pharmaceutical Equipment
During pharmaceutical production, many devices require prolonged contact with medicinal solutions, solvents, and cleaning agents. S355J2WP Weather Resistant Steel plate, with its excellent corrosion resistance, is suitable for pharmaceutical reaction vessels, storage containers, and piping systems. It minimizes contamination risks from corrosion, ensuring high purity and stability in drug manufacturing.
Chemical Processing Equipment
The chemical industry frequently involves acids, alkalis, salts, and various corrosive media, demanding durable and reliable equipment. This steel grade performs exceptionally well in chemical reactors, pressure vessels, and piping systems, extending equipment lifespan and reducing maintenance costs.
Seawater Equipment
Marine environments feature high salinity and intense humidity, causing ordinary steel to rust rapidly. S355J2WP High Strenhth Weather Resistant Steel Plate is suitable for desalination plants, seawater pipelines, and port structures, effectively resisting salt spray corrosion.
Heat Exchangers
During thermal cycling, materials endure temperature fluctuations and condensate exposure. S355J2WP offers superior corrosion resistance and thermal stability in heat exchangers, ensuring efficient heat transfer and long-term operational reliability.
Condensers
Condensers are typically exposed to humid environments or media containing corrosive gases. Weathering steel effectively prevents pitting and crevice corrosion, maintaining system efficiency and stability.
Paper Industry
Paper manufacturing involves acidic/alkaline solutions and bleaching agents that severely corrode equipment. S355J2W can be used in digesters, bleaching tanks, pulp storage tanks, and similar equipment, enhancing durability and reducing maintenance frequency.
Offshore Oil Drilling Companies
Offshore platforms endure prolonged exposure to sea winds, salt spray, and moisture in marine environments. S355J2W is suitable for drilling rigs, support structures, and subsea pipeline systems, delivering reliable structural strength and corrosion resistance.
Power Generation
In power plants-particularly coal-fired and biomass facilities-equipment frequently faces high-temperature flue gases and condensate water, leading to significant corrosion challenges. S355J2W can be used in boiler components, exhaust pipes, and cooling systems to extend overall service life.
Petrochemical Industry
Oil and gas processing involves high temperatures, pressures, and sulfur-containing environments. Weathering steel resists corrosion and cracking in storage tanks, pipelines, and heat exchangers, enhancing safety.
Gas Processing
During natural gas purification and industrial gas production, equipment must withstand corrosive gases like CO₂ and H₂S. S355J2W is suitable for gas storage tanks, separation units, and transmission pipelines, reducing leakage risks caused by corrosion.
Specialty Chemicals
Production of specialty chemicals like coatings, dyes, and catalyst feedstocks often involves highly corrosive solutions. This steel maintains excellent stability in storage tanks and reaction vessels, ensuring continuous production and equipment safety.
