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 A514 Gr R alloy steel plate 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 A514 Gr R alloy steel plate rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
The toughness of steel such as A514 Gr R alloy steel plate is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
S355J0 steel is a low alloy structural steel. We can supply S355J0 structural steel plates up to 400mm, with a minimum yield strength 355MPa when plate thickness less than 16mm, min. yield strength 345MPa when plate thickness range 16mm to 40mm. Without any special rolling or heat treatment for S355J0 steel plate and sheet, A514 Gr R alloy steel plate, the abbreviated designation of this delivery condition shall be AR (As rolled).
Recently, a symposium on the celebration of the 70th anniversary of the founding of the People's Republic of China by the iron and steel industry was held in Beijing Convention Center. The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, BBN A514 Gr R alloy steel plate Steel Staff sang songs to the mark the 70th victory anniversary. In the last of September, Henan BBN Steel organized all employees to sing ""My Country and I"" and made a film.
