The effect of nitrogen (N) on the properties of differences between a573 grade 70 and a516 grade 70 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 differences between a573 grade 70 and a516 grade 70 steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
