The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of PVQ HII steel boiler steel plate cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.PVQ HII steel boiler steel plate,The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.PVQ HII steel boiler steel plate,We can produce steel plate, steel pipe, steel coil, and also carry out a series of processing services, steel plate cutting, welding, etc. we have advanced production technology and production equipment, which can meet the needs of customers to the greatest extent. Whether it is deep processing or cutting, we will communicate with customers in detail to choose the best processing method and production technology.PVQ HII steel boiler steel platePVQ HII steel boiler steel plate,The effect of alloy elements of Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.The company has a professional after-sales service team and good after-sales service reputation, providing full and uninterrupted after-sales service, to ensure timely and rapid solution to customer problems. The company is recognized as a 5-star brand of market quality cost performance and customer satisfaction by Market Research Center, and rated as "AAA credit enterprise of enterprise credit evaluation", and also a leading steel producer and service provider in the world.
