Published: Feb 2, 2026 14:55
Recently, the R&D of Jinye Huaxi Special Steel's medium-thickness plate Q355ND has been successfully completed. The product specifications cover 12–50 × 2,000–2,500 mm, with all performance indicators meeting the requirements of the GB/T1591-2018 standard, and some key parameters surpassing those of similar international products. This marks a significant breakthrough for Huaxi Special Steel in the field of low-alloy high-strength steel. The Q355ND steel plate exhibits excellent weldability, cold formability, and fatigue resistance, making it suitable for widespread application in various high-end fields such as building construction, bridge construction, marine engineering, energy equipment, and rail transportation.

[Grain-Oriented Silicon Steel Prices Will Remain in a Consolidation Trend Next Week, with Limited Fluctuations] Market feedback indicated that the current core downstream demand mainly came from transformer manufacturing enterprises. Affected by the industry's traditional off-season, enterprises had weak purchase willingness and mostly adopted strategies of consuming their own inventory and making small-volume replenishments on demand. Acceptance of current prices remained stable, but there was a lack of momentum for large-scale procurement, resulting in relatively weak actual transaction performance for grain-oriented silicon steel. Due to inventory pressure on some specification resources, traders had limited room for slight discounts.
