    Outstanding problems in the development of China's stainless steel flange industry

    The production capacity will be severely surplus. At present, my country has formed a production capacity of more than 16 million tons of stainless steel flanges. According to estimates, the production capacity of stainless steel flanges under construction and proposed is also more than 10 million tons. In the next few years, the contradiction that the actual production capacity of stainless steel flanges exceeds market demand will become increasingly prominent.

    The industry concentration is not high. The stainless steel flange output of Taiyuan Iron and Steel and Baosteel accounts for less than half of the national output, and the proportion of these two major stainless steel flange enterprises is even lower in terms of production capacity. The ratio in Europe and South Korea is more than 3/4. Counterfeit and inferior products seriously endanger the healthy development of the industry. In recent years, “counterfeit and inferior 200 series” has been severely flooded, wasting precious and scarce resources such as nickel and manganese, disrupting normal order, infringing on the interests of consumers, polluting stainless steel flange scrap resources, and seriously jeopardizing the stainless steel law The healthy development of the orchid industry.

    There is still a certain gap between the physical product quality, main economic and technical indicators, variety structure and other aspects of the international advanced level.

    The recycling of waste in the production, deep processing, and consumption of stainless steel flanges, as well as the recycling of waste nickel and chromium in other industries, needs to be further strengthened. The development and utilization of stainless steel flange resources also requires greater investment.
