The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the EN10025-4 steel S275M industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the EN10025-4 steel S275M industry with scientific management, high quality, first-class service and harmonious development

Q460C application: It is a material used for stamping of high-demand products such as auto parts and electrical parts, with high tensile strength and good toughness. Various cold punching dies and tools with complex shapes and heavy working conditions, such as punching dies, trimming dies, hemming dies, deep drawing dies for steel plates, circular saws, standard tools and gauges.

Alloy steel seamless pipe is a kind of high-quality seamless steel pipe with outstanding performance and characteristics. The alloy steel seamless pipe has excellent high-pressure resistance and can withstand greater pressure. Even under pressure, the EN10025-4 steel S275M, alloy steel seamless pipe is not easy to break, and it is more safe and reliable to use. It also reduces the loss of pipe material and reduces the maintenance work of pipeline.

Composition characteristics of low alloy structural steel, EN10025-4 steel S275M: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our EN10025-4 steel S275M products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
