The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, high strength Hardox 450 steel flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

Imposition of tariffs moves the demand towards domestic high strength Hardox 450 steel steel companies, but it does not help in addressing the supply situation, which still remains low domestically. American steel consuming industries have to now pay higher taxes to the federal government for these imports. We had seen a similar decline in high strength Hardox 450 steel US Steel’s stock price when tariffs were imposed by the Bush administration.

The effect of nitrogen (N) on the properties of high strength Hardox 450 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 high strength Hardox 450 steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
