Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.Steel GB Q345D Plate,The company adopts the international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety management system, and has realized the comprehensive integration of the three systems In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group,Steel GB Q345D Plate.The correct choice of billet type, section shape, size and weight are of great significance to steel rolling production Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality The consideration of these technical requirements is necessary to ensure the quality of steel It should also be specifically considered when determining and selecting the blank The rolling method can be divided into cold rolling and hot rolling according to the rolling temperature,Steel GB Q345D Plate.Steel GB Q345D 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,Steel GB Q345D Plate.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.
