Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A588 grade B high strength steel based on a high starting point and high technology, the company has vigorously developed various steel products A588 grade B high strength steel and deep-processed parts, steel structures, precision castings, seamless pipes.
In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the A588 grade B high strength steel steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the A588 grade B high strength steel steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of A588 grade B high strength steel seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
On September 14th 2019, a Australia customer purchased 500 tonsDIN17155 15Mo3 boiler steel plates, which will be used for vessel modification of wax backflow protection project and LPU project. Many old customers keep asking about Din17155 steel grade-15Mo3. Usually our company would suggest customers to choose EN10028 steel specification, but if customer insiste on the old steel grade, we could arrange it either. With years of experience in produceing DIN 17155 15Mo3 boiler steel plates, the company supplies high quality steel A588 grade B high strength steel product with low cost and better service.
The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, A588 grade B high strength steel.
Aspire to technological innovation and pursue first-class quality steel A588 grade B high strength steel products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.
