S355J2+N Plates Features

• » Normalized Microstructure (+N): Undergoes a controlled thermal cycle to achieve a fine-grained, uniform structure, ensuring consistent mechanical properties even in heavy-wall sections.
• » Enhanced Fracture Toughness: The "J2" impact testing ensures the material resists brittle fracture with a minimum energy absorption of 27 Joules at -20°C, ideal for sub-zero operating conditions.
• » Superior Through-Thickness Ductility: Normalizing reduces internal stresses and improves Z-direction properties, critical for joints subjected to high lamellar tearing risks.
• » Excellent Weld Integrity: Designed with a low carbon equivalent (CEV), these plates offer exceptional weldability, maintaining the strength and toughness of the heat-affected zone (HAZ).
• » Dimensional Stability: The stress-relieved nature of the normalized state minimizes warping and distortion during precision laser, plasma, or flame cutting operations.
• » Optimized Cold Forming: The refined grain structure allows for tight bending radii and complex forming without surface cracking, essential for manufacturing curved structural profiles.
• » Reliable Machinability: Consistent hardness and a clean metallurgical structure result in predictable tool wear and superior surface finishes during drilling, milling, and tapping.
• » High Strength-to-Weight Ratio: With a 355 MPa minimum yield strength, it enables the design of lighter, more efficient structures without compromising safety or structural rigidity.
