By Region: data shows that in the first quarter of Asia, crude steel CCS grade D bulk carriers steel production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year.
The effect of nitrogen (N) on the properties of CCS grade D bulk carriers 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 CCS grade D bulk carriers steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
