S355K2W steel plate is an improved atmospheric corrosion-resistant steel. The S355K2W material number is 1.8967. The V-shaped impact test temperature of S355K2W steel is -20 degrees, and the minimum energy is 27J. Improved atmospheric corrosion-resistant steel refers to weather-resistant steel or atmospheric corrosion-resistant steel.
S355K2W steel plate, "S" indicates that the S355K2W grade can be used in steel structure engineering, and 355 is the minimum yield strength. The J0, J2, and K2 standards are the impact degree and energy at -20°C. "W" indicates mainly differences in carbon and phosphorus content and utilization.
