EN 10025 S420ML steel chemical elements composition

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, EN 10025 S420ML steel based on a high starting point and high technology, the company has vigorously developed various steel products EN 10025 S420ML steel and deep-processed parts, steel structures, precision castings, seamless pipes.

In August 2011, the expanded license for the special equipment material manufacturing of EN 10025 S420ML steel steel plates for heavy steel boilers and pressure vessels successfully passed the expert review and identification. At this point, the company has the qualification to produce steel plates for boilers and pressure vessels with a maximum thickness of 80 mm. Production continues to be at the leading domestic level. Our boiler steel plate has been widely used in the EN 10025 S420ML steel manufacture of I, II, III pressure vessels and various pressure vessel reaction tanks.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from EN 10025 S420ML steel. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.

EN 10025 S420ML steel, 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.
