Our company was founded in 2000, which initially committed to providing high-quality steel EN10025-4 steel S275ML 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 EN10025-4 steel S275ML steel to the international market, opening up the international steel market.

Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished EN10025-4 steel S275ML steel plates products according to the client needs. Realize the service from product drawings-steel plate procurement-steel plate cutting-steel plate processing EN10025-4 steel S275ML steel plate distribution services, so as to save customers manpower and material resources.

The company always adheres to the concept of green production, follows the development path of innovation, transformation and improvement, and has carried out in-depth cooperation with Zhengzhou University and other scientific research institutes, planning from a high starting point, strict standard design, and successfully implementing engineering projects With nearly 20 research and development projects, the company's production technology and equipment are at the forefront of the industry, and indicators such as environmental protection, energy consumption, cost, and resource utilization have reached the advanced level in the industry.

EN10025-4 steel S275ML, Q390B steel plate generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling. During smelting, The scrap steel is added to the furnace along with the charge and smelted according to the conventional process. After tapping, the deoxidizer and alloy are added. After the molten steel is treated by argon blowing, it is cast immediately. Rare earth elements are added to the steel, the Q390B steel plate is purified, and the content of inclusions is greatly reduced.
