The company revolves around the long-term strategy of "building a quality base and building a century-long BEBON", adheres to the development ideas of innovation, transformation, and improvement, vigorously promotes transformation and upgrading, structural adjustment, energy conservation and emission reduction, and strives to create high-quality steel with strong core competitiveness and distinctive features The production base has become a green steel city with intensive land use, clean production, efficient use of resources, harmonious and friendly production and environment, business and society, and BEBON characteristics.
A709 Gr HPS70W bridge steel plate, 12Cr1MoV steel is alloy structure steels, and it is usually produced into 12Cr1MoV steel coil, 12Cr1MoV steel sheet, 12Cr1MoV steel plate, 12Cr1MoV steel bar, etc. 12Cr1MoV steel is composed of Carbon, Silicon, Manganese, Chrome, Molybdenum and so on chemical elements. Amng them, the C content is 0.08-0.15, Si 0.17-0.37, Mn 0.40-0.70, Cr 0.90-1.20, Mo 0.25-0.35. The tensile strength of 12Cr1MoV steel is not lower than 490 Mpa, and yield strength is not lower than 245 Mpa.
The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. A709 Gr HPS70W bridge steel plate, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
We have new significant A709 Gr HPS70W bridge steel plate projects in Nigeria. It is about crude oil storage tanks. With the development of our steel materials business in the Africa those years, Nigeria has been an important market to us. And we have many A709 Gr HPS70W bridge steel plate famous projects in local and also participated in a lot of governmental projects. This crude oil storage tanks project is a very big engineering, and lasts for years. This is the only initial stage. We are under negotiation about following installation and further demands etc. matters.
Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
At present, the overall market demand of A709 Gr HPS70W bridge steel plate is weak, the purchase intention of end users is not strong, and the purchase is basically on demand. The market transaction of A709 Gr HPS70W bridge steel plate is relatively general, and some markets have declined. However, the overall market inventory of A709 Gr HPS70W bridge steel plate is not high, coupled with the strong willingness of steel mills to support price, and the high resource cost in the later stage, therefore, businesses are not willing to sell of A709 Gr HPS70W bridge steel plate at too low price. On the whole, the short-term market of A709 Gr HPS70W bridge steel plate is expected to be dominated by high fluctuations.
