Wenfeng Special Steel Company Successfully Conducted Research and Trial Production of 150mm Thick Q355NE Normalized Steel Plate

Warmly congratulate Wenfeng Special Steel Company on the successful research and trial production of 150mm thick Q355NE normalized delivery steel plate.
Q355NE steel plate has the characteristics of high strength, good plasticity, strong weldability, and excellent low-temperature impact toughness of minus 40 degrees. It is widely used in wind power equipment, high-rise buildings, bridge structures, mining and metallurgical machinery and other fields.
The product technology team of the Special Steel Company actively implemented the group's strategic deployment on vigorously developing new varieties. In response to the market demand for thicker Q355NE steel plates, the company's deputy general manager Zhao Wenzhong proposed a plan at the technical quality meeting, requiring the use of applicable waste material billets to conduct scientific research and trial production of 150mm thick Q355NE normalized delivery steel plates, so as to achieve both speed and reduce R&D costs.
The Technology Center actively implements work requirements, organizes chief engineers to develop test plans, and assigns specific professional and technical personnel to track the entire process of billet heating, rolling and controlled cooling processes, heat treatment test processes, ultrasonic flaw detection, performance sampling inspection, metallographic inspection, and other work. At the same time, the relevant data results are summarized promptly to form a reasonable large-scale production heat treatment process.
With the joint efforts of the technical center, rolling mill, quality inspection department and steelmaking plant, the scientific research and trial production of the large-scale production process of 150mm thick Q355NE normalized delivery steel plate was finally successful, which expanded the performance-guaranteed process thickness specifications of Q355NE steel plates, enriched the thick plate variety structure of the special steel company, and laid a solid technical guarantee foundation for the smooth acceptance of future Q355NE thick steel plate contracts.
