Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
The pipeline steel coil and plates are our main products. And the most popular standard for pipeline steel is API 5L. We mainly supply API 5L grade B (L245), API 5L X42 (L290), API 5L X46 (L320), API 5L X52 (L360), API 5L X56 (L390), API 5L X60 (L415), API 5L X65 (L450), API 5L X70 (L485) pipeline steel coil and plates. Those stteel grades have both PSL1 and PSL2 levels. PSL2 has more strict requirements than PSL1. Besides, we also supply API 5L grade A PSL1 and API 5L X80 PSL2 steel.TB/T 1979 08CuPVRE Chinese steel grade
SA516 gr60 boiler plates are primarily intended for use by pressure vessel fabricators and manufacturers And, physical and chemical characteristics of the boiler quality plates make these a popular choice in the industries SA516 gr60 boiler steel plates are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built Also, these plates are repellent to corrosion and therefore is long-lasting and can also be used in different environments for a long time without any deterioration,TB/T 1979 08CuPVRE Chinese steel grade.
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
On August 29th Clients from Senegal visited us-Zhengzhou office and wanted to know more about BBN to build a long relationship. They have a big demand of ship building steel plates with thickness 6mm and thickness 8mm LR AH36 shipping steel plates to Senegal Navy, and our strong advantage in offering these ship building steel plates make us begin to build a steady cooperation relationship with Senegal clients. BBN has always supplied high quality ship plates with stable supply. Soon he placed 15 containers of LR AH36 shipping steel plates to BBN.
S355NL steel plate, under EN10111 standard S355NL steel plate, under EN10111 standard, we can regard S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EETB/T 1979 08CuPVRE Chinese steel grade
