S355J2+2 Round Bar Overview
S355J2+N is a normalized structural steel grade offering a minimum yield strength of 355 MPa and superb impact resistance down to –20°C. The 'J2' signifies a 27 Joule minimum impact energy at sub-zero temperatures, while 'N' refers to the normalization heat treatment, enhancing the steel’s toughness and internal grain uniformity. This makes it the material of choice for critical load-bearing applications.
S355J2+N round bars are high-strength structural steel bars widely used in construction, heavy machinery, and engineering applications. These bars comply with European EN 10025 standards, ensuring excellent toughness, weldability, and impact resistance at low temperatures.
