In recent years, in line with the development trend of iron and steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
A514 grade B high strength steel,Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. , Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace The smelting process is Ca-treated, and should be intrinsically fine-grained steel The actual grain size is 5 or above,A514 grade B high strength steel.

The correct choice of billet type, section shape, size and weight are of great significance to steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, steel sheets, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
According to the data of the Bureau of statistics, the average monthly output of domestic steel in the past five years (2015-2019) is 96.8696 million tons. In recent five years (2015-2019), the average monthly export volume of domestic steel is 7.2152 million tons, accounting for 7.45% of the average monthly steel output. The top 10 major exporters are South Korea, Vietnam, Thailand, Indonesia, the Philippines, India, Myanmar, Saudi Arabia, the United Arab Emirates and Malaysia, accounting for 51.4% of the total domestic exports.
