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, RINA grade A floating dock steel based on a high starting point and high technology, the company has vigorously developed various steel products RINA grade A floating dock steel and deep-processed parts, steel structures, precision castings, seamless pipes.
Heat-resistant steel thick plate is made of heat-resistant steel and is processed by hot rolling. According to different structure characteristics, it can be divided into four types: austenitic type, ferrite type, martensite type and precipitation hardening type. RINA grade A floating dock steel, The heat-resistant steel plate is widely used in the manufacture of petroleum, chemical equipment, boilers, steam turbines, industrial furnaces and other components and other components working at high temperatures.
The advantages of RINA grade A floating dock steel, carbon steel: First of all, the price of carbon steel is low. Compared with stainless steel, galvanized steel, alloy steel, etc., the carbon steel has a great advantage in price. It is a good choice for manufacturers and merchants such as construction sites that use building materials in large quantities. Secondly, the carbon steel is easy to process. In the early days, steelmaking technology was underdeveloped. It was very difficult to manufacture high-precision steel, and carbon steel is widely used.
For wear-resistant steel plate, it is not the higher the hardness, the better the wear resistance! Hardness is the basis of excellent wear resistance of RINA grade A floating dock steel, wear-resistant steel plate, but the relationship between hardness and wear resistance is not in direct proportion. The reason why wear-resistant steel plates are wear-resistant is that they have hard particles and soft matrix. Generally, in the process of wear, there will be some falling substances, which will be incorporated into the soft matrix and will not cause great damage to the surface.
RINA grade A floating dock steel, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.
The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products RINA grade A floating dock steel and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.
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, RINA grade A floating dock steel sheet, 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!
