S355JO+N Plates

roduct Overview:
S355JO+N Plates are normalized structural steel plates conforming to EN 10025-2 standards. The “+N” designation indicates that the material is normalized, which enhances its mechanical properties, toughness, and structural integrity, especially for demanding applications. These plates offer minimum 355 MPa yield strength and are impact-tested at 0°C, making them ideal for structural applications in moderate climates.

🔍 Key Features:

• Minimum yield strength of 355 MPa

• Normalized (+N) for improved strength and toughness

• Excellent weldability and formability

• Impact-tested at 0°C for enhanced structural performance

• Low carbon equivalent – ideal for cold-forming and welding
