321 stainless steel price trend and purchasing guide in 2025: Insight into market dynamics and optimize purchasing strategies
I. Current domestic market price situation
In 2025, the domestic 321 stainless steel price showed a stable fluctuation trend, mainly affected by raw material costs, supply and demand relations and industry policies.
Plate price: The unit price of hot-rolled plates with a thickness of 3-20mm is concentrated in 20.6-22.3 yuan/kg, among which the price of 3-10mm specifications is relatively uniform, and the thickness above 12mm gradually increases due to the increased difficulty of processing.
Coil price: The price of 321 stainless steel coil is about 17,000 yuan/ton, which is suitable for bulk purchase needs.
Seamless pipe price: The price of large-diameter (such as DN150) hot-rolled seamless pipe is about 17,800 yuan/ton, and the cost of thin-walled pipe is higher due to the complex process.

Sheet/coil: The quotation range is $1,000–2,500/ton, depending on the surface treatment (such as BA, 2B), minimum order quantity and transportation cost.
Bar: The export price of bars is about $1,991.75/ton, which is suitable for high-precision equipment manufacturing needs.
3. Key factors of price fluctuations
Raw material cost: The prices of alloy elements such as nickel and molybdenum directly affect the cost of 321 stainless steel.
4. Procurement strategy recommendations
Specifications and surface treatment: For conventional industrial purposes, 2B surface hot-rolled plates (lower cost) can be selected; for the food and pharmaceutical industries, BA tubes (higher finish, 15-25% higher price) are preferred; large-diameter seamless tubes are recommended to be customized to avoid inventory backlogs.
The 321 stainless steel price trend shows a clear upward trajectory driven by global industrial demand and raw material volatility. To avoid rising costs, buyers are advised to lock in their orders now.
