On Nov. 1st, 2019, BBN A572 grade 55 high strength steel steel organized Delegation to visit Zhengzhou Children Welfare Institute, and to give sponsorship as well as concerns to the Children. The handicapped children is always a pain topic. With the development of the society, they also gets increasing concerns and help from all walks of life. Thankfully, our Government also gives high concern to the handicapped children and has built A572 grade 55 high strength steel Children Welfare Institutes all over the country to guarantee their lives.
The company has a group of mature steel plate production and processing line construction and production management experience. In addition, the company has professional and technical personnel. BBN steel is a modern enterprise integrating scientific research and development, production processing, sales and service. The company now has finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. At the same time, it also adheres to international standards and adheres to the international line.
Q345B material is a low-carbon alloy steel (c <0.20%), with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345R steel is a special plate for pressure vessels with a yield strength of 345MPa. It has good comprehensive mechanical properties and technological performance. In addition to the tensile strength and elongation requirements higher than Q345 (16Mn) steel, Q345R is also required to ensure impact toughness.
The carbon content of A572 grade 55 high strength steel, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
We have lots of successful cases, for example in July 2015, we exported 5714 tons ASTM A36 mild steel plate to Peru. After receiving the plates and putting then into use, our customer spoke highly of the ASTM A36 mild steel plate quality. In addition, the customer also introduced us an Venezuela customer, who bought 933 tons A36 steel A572 grade 55 high strength steel plate from us. And then in Mar. 2016, due to the first cooperation in July 2015 is very successful. The customer is very satisfied with our product quality and comprehensive service. This time, the customer place an 3989 tons order directly.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled A572 grade 55 high strength steel plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive A572 grade 55 high strength steel industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
