Product Overview –S355J2+N Welded Pipes
S355J2+N Welded Pipes are high-strength structural steel pipes manufactured from normalized or normalized rolled EN-grade steel, offering excellent weldability, outstanding toughness, and reliable mechanical performance. Designed for demanding structural and industrial applications, these pipes are widely used in construction, offshore projects, oil & gas facilities, power plants, heavy engineering, bridges, and infrastructure developments.
The "+N" normalized condition improves grain structure, resulting in enhanced strength, uniform mechanical properties, and dependable performance even under low-temperature service conditions. The J2 designation indicates impact testing at -20°C, making S355J2+N Welded Pipes suitable for projects requiring higher toughness than standard structural steel pipes+.
