What are S355J2+N Steel Plates?
S355J2+N Steel Plates are high-strength low-alloy structural steel plates manufactured according to EN 10025-2 standards. The grade offers a minimum yield strength of 355 MPa and excellent impact toughness at -20°C, making it suitable for demanding structural and engineering applications. The +N designation indicates that the steel has been supplied in a normalized or normalized rolled condition, resulting in improved grain structure, better weldability, enhanced toughness and consistent mechanical properties. These plates are widely used in bridge construction, offshore platforms, heavy engineering, earthmoving equipment, pressure vessels, cranes, mining projects, industrial buildings and renewable energy structures where high strength and reliability are critical. At Triton Alloys Inc., we stock and export S355J2+N steel plates in various thicknesses, widths and custom cut sizes with Mill Test Certificates, third-party inspection and worldwide delivery.

Frequently Asked Questions (FAQs) on S355J2+N Steel Plates
S355J2+N is a high-strength, low-alloy structural steel grade known for excellent weldability, toughness, and durability. Supplied in normalized (+N) condition, these plates offer superior impact resistance at temperatures as low as -20°C, making them ideal for heavy engineering, offshore structures, bridges, and pressure vessel applications.
The “+N” indicates that the steel plate has been supplied in a normalized condition. Normalizing refines the grain structure, enhances mechanical properties, improves machinability, and ensures better dimensional stability under heat and pressure.
S355J2+N steel plates provide a minimum yield strength of 355 MPa, making them suitable for high-load structural applications.
S355J2+N plates are widely used in bridge construction, offshore structures, industrial buildings, power plants, mining equipment, oil & gas facilities and heavy engineering projects.
At Triton Alloys Inc., we stock S355J2+N plates in thicknesses ranging from 6 mm to 300 mm
and widths up to 3500 mm. Custom cut-to-size and value-added services like plasma cutting,
profile cutting, and edge preparation are also available on request.
