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.

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 EN10025-4 S460ML steel 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.

EN10025-4 S460ML steel 2020 spot size: 16*1800*6000, 15*2500*10000, 25*2400*8200, 50, 25*2400*8200, 16*2000*10713, 25*2400*8200, 16*2270*11900, 15*2500*10000, 25*2400*8200, 28*2170*13000, 130*2200*7700, 100*1770*6650, 88*3440*9200, 12*2200*8000, 8*2200*5730, 16*2320*10000, 30*2400*9680 12*2200*8000, 16*1800*6000, 50*1820*10700, 130*2200*7700.

Compared with EN10025-4 S460ML steel, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while EN10025-4 S460ML steel is not.

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.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality EN10025-4 S460ML steel products and excellent services. Our company's products EN10025-4 S460ML steel are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.
