The S355J2WP rusty steel stainless steel 2250 mm wide coil mill has advantages such as adapting to difficult-to-deform steel grades. The Liuzhou Iron and Steel Hot Rolling Leveler project designed and supplied by MCC South is equipped with the latest straightening and leveling process (LTP technology) developed by MCC South. The S355J2WP rusty steel performance stability, cost and various consumption indicators have reached the international advanced level.

The effect of nitrogen (N) on the properties of S355J2WP rusty steel and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in S355J2WP rusty steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
