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 Gr C structural steel plate based on a high starting point and high technology, the company has vigorously developed various steel products A588 Gr C structural steel plate and deep-processed parts, steel structures, precision castings, seamless pipes.
The company supplies more than 2,000 tons of pressure vessel steel materials to the Nigerian customer for the construction of atmospheric pressure tower in the refinery. This batch of A588 Gr C structural steel plate pressure vessel steel materials are tailored according to customer requirements, and the composition and process are newly designed. The performance of the pressure vessel steel materials meets the requirements of properties such as resistance to tempering embrittlement and hydrogen corrosion, and A588 Gr C structural steel plate special properties such as good formability, weldability and adaptability to welding process.
20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. A588 Gr C structural steel plate, 20# steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. 20# steel performance is basically similar to 15# steel, but the strength is slightly higher. The cold-drawing or normalizing state of the cutting process is better than the annealing state. 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness.
If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with A588 Gr C structural steel plate, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.
BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, A588 Gr C structural steel plate , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.
