The price of 2507 stainless steel pipes continued its downward trend, but the decline narrowed significantly. This week, the futures market saw a sharp drop, influenced by the plunge in gold and silver prices, leading to consecutive days of decline in ferrous metal prices. Although there was a slight rebound mid-week, the upward momentum was clearly insufficient, and the downward trend continued. However, compared to other commodities, prices remained relatively stable, especially with the approaching Spring Festival holiday, most traders had little incentive to adjust prices. Regionally, participation in the northern market decreased significantly, resulting in a marked reduction in transaction volume. Meanwhile, in Central and Southwest China, pre-holiday restocking increased. As 2507 stainless steel pipe prices stabilized, demand increased, leading to increased transaction volume. In East and South China, some traders continued to reduce inventory through price cuts. Nationwide, market performance varied. However, towards the end of the week, both buyers and sellers in the 2507 stainless steel pipe market gradually withdrew, resulting in a “statically stable” price in the absence of transactions. Stainless steel spot supermarkets anticipate the 2507 stainless steel pipe market entering a closed period, with prices remaining frozen and stable.
