A588GrC landscape used steel social inventory fell sharply

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the A588GrC landscape used steel steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

The longitudinally welded pipe trial-produced with BBN steel's X120 pipeline steel plate has recently passed the inspection of the Pipe Research Institute of China National Petroleum Corporation, which means that my country can produce more difficult pipeline steel welded pipes. BBN steel has become the leading domestic X120 pipeline steel trial production Ability of the enterprise.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for A588GrC landscape used steel and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

How to quickly judge whether the price of A588GrC landscape used steel, weathering steel plate is reasonable? What are the factors influencing the price quotation of A588GrC landscape used steel, weathering steel plate? First of all, the material composition of weathering steel plate is different, and the corresponding performance and price are also different. Therefore, when we talk about the price of A588GrC landscape used steel, weathering steel plate, we should first make clear of the material composition. Secondly, the specification especially the thickness of the A588GrC landscape used steel, weathering steel plate will affect the quotation. Generally, the thicker the weathering steel plate, the higher the price.
