BBN Group supply 1650tons weather resistant SA588 grade B steel to Netherlands

The effect of nitrogen (N) on the properties of weather resistant SA588 grade B 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 weather resistant SA588 grade B steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

Tianjin warehouse mainly stores steel plates and steel pipes. The monthly replenishment is about 12000 tons. Our inventory cycle is short and flexible. Shanghai warehouse mainly stores weather resistant SA588 grade B steel ,steel plate and section steel. The average monthly purchase volume is about 15000 tons. The geographical location of the warehouse has greatly improved our performance in terms of transportation and delivery time.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled weather resistant SA588 grade B steel products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the weather resistant SA588 grade B steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

As we are supplying EN 10028-3 Grade P355NH fine grained structure steel plates and weather resistant SA588 grade B steel in China since 2008 to many petrochemical companies and in energy sector industries. We have become a preferred hot-rolled plates supplier in China.
