The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A588 grade B high strength steel nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A588 grade B high strength steel steel, can be used as an alloying element of low alloy steel.
According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw A588 grade B high strength steel steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the A588 grade B high strength steel market due to the impact of the closure of local steel mills in Italy.
High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the A588 grade B high strength steel, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.
