Welcome to BBN High Strength Steels Factory
Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional S460QL steel tubing production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of S460QL steel tubing leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
After years of operation and accumulation, the company has formed an operation network covering major economic cities across the country, with a group of high-quality professional logistics technicians and management personnel, strong strength and stable logistics channels. The company's business operations include the loading and unloading of steel raw materials and finished materials, S460QL steel tubing warehousing, and freight transportation. Our logistics service business has passenger transportation, automobile and construction machinery inspection, logistics information management and operations.
The S460QL steel tubing steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the S460QL steel tubing internal quality of the steel.
In December, 2018, our Vietnam customer purchased 352 tons SA387Gr12Cl2 and SA387Gr11Cl2 S460QL steel tubing steel plates for their tank fabrication project. The customer need those cargo urgently, and we keep many stock in warehouse , it only takes about 3days we collect total cargo for shipping to customer. The customer are very appreciate our quality and service. They S460QL steel tubing become our regular customer and repeat order to us every month.
S460QL steel tubing, St52-3 steel is a low alloy, high strength structural steel which can be readily welded to other weldable steel. St52-3 steel’s mechanical properties is yield strength more than 355 MPa, tensile strength 490-630Mpa. For St52-3 steel, the C element content is 0.24%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.045% max, the S element content is 0.045% max.
