Welcome to BBN High Strength Steels Factory
The company formulates appropriate S960QL steel properties product internal control components, strictly controls the fluctuation range of chemical components, and ensures the stability of steel plate performance. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate.
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, S960QL steel properties based on a high starting point and high technology, the company has vigorously developed various steel products S960QL steel properties and deep-processed parts, steel structures, precision castings, seamless pipes.
Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.
The effect of alloy elements of S960QL steel properties, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
