Our company was founded in 2000, which initially committed to providing high-quality steel BV grade A ferry steel plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export BV grade A ferry steel plate steel to the international market, opening up the international steel market.
The quality of BV grade A ferry steel plate shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of BV grade A ferry steel plate buyer, such as packaging, delivery time, etc.. On the basis of the quality of BV grade A ferry steel plate in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of BV grade A ferry steel plate and certain performance limit of BV grade A ferry steel plate, etc.
Alloy steel plate is a kind of high strength steel plate with excellent performance in all aspects. In the current market environment, the performance requirements for steel plate are also higher and higher, ordinary steel plate has been far from meeting the market demand, and the emergence of alloy steel plate has broken this deficiency. The alloy steel plate is improved from the traditional steel plate, which is a new high improvement to the performance of the traditional steel plate. Today let us have a learn of BV grade A ferry steel plate, alloy steel plate together.
After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, BV grade A ferry steel plate.
10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. BV grade A ferry steel plate, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.
