Recently, all the new products developed by Hebei Iron and Steel Company – the 09MnNiDR (HIC) steel plates resistant to HIC corrosion and suitable for use in thick sections at ultra-low temperatures – were delivered to customers. Upon retesting back at the factory, 100% of these plates met the required standards, earning high praise from the users. This steel grade is a new type developed in China for the first time; it has successfully replaced imported materials and will be used exclusively in the manufacturing of key equipment for a large-scale petrochemical project in the country. The market share of 09MnNiDR steel plates ranks among the highest in the industry. The new 09MnNiDR (HIC) steel plate boasts exceptional resistance to HIC corrosion; its maximum thickness is 105 mm. The design requirements specify that the layer at 1/2 of this thickness must be able to withstand impacts at ultra-low temperatures of -70°C, making its technical production one of the most challenging in China. Angang adheres to a strategy focused on high-end, high-quality products, deeply optimizes its \"two structures,\" promotes technological upgrades across the board, increases efforts in developing new products, and strives to create more products that can stand out as industry leaders. To meet customers’ specific requirements such as high toughness and resistance to HIC corrosion, technical staff work closely with the customers. Drawing on extensive previous production experience, they develop customized manufacturing processes tailored to the characteristics of each order, thereby effectively integrating customer needs with process control. During the production process, quality improvement efforts were undertaken; through various innovative approaches such as high-purity smelting processes and heavy reduction rolling techniques, multiple technical challenges were overcome, including the control of inclusion levels and the uniformity of the steel ingots’ ends and centers, ensuring that the steel plates were delivered to customers in high quality.
It’s tough in the scorching summer heat! Keep up with heat prevention and cooling! Clarify the key tasks! Safety analysis must not be neglected! ----------------------------------------------The past decade has been a period of rapid development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which has contributed to the swift advancement of the petrochemical sector.
