When your project involves extreme temperatures, oxidizing environments, and requirements for a long service life, selecting the wrong material can result in downtime losses and replacement costs that often run into the thousands. For this very reason, an increasing number of engineers and procurement specialists are turning to 310 stainless steel plates. What is the latest market unit price (per kilogram) for 310 stainless steel plates? It is a figure well worth knowing!
This guide provides you with actionable market insights, an analysis of factors influencing pricing, and expert procurement strategies-helping you not only to purchase more affordably but, more importantly, to purchase more wisely.
SS 310 Plate Price per kg (2026 Latest Market Range)
The price of 310S stainless steel plate generally ranges from $1,000 to $2,500+ per ton for bulk, or roughly $1.10 to $4.00 per kilogram (approx. $0.50–$1.80 per pound). Prices vary based on thickness, finish, and supplier, with specific industrial pieces costing more.

Is there a price difference between 310 and 310S?
The difference is negligible. 310S is the low-carbon version of 310 (with a carbon content of ≤ 0.08%). In today's market, most steel mills produce 310/310S steel that carries "dual certification." The prices for both are typically identical; however, for various applications involving welding, 310S is often the preferred choice.
Key Factors Influencing the Price of SS 310 Stainless Steel Plates
1. Raw Material Costs (Nickel and Chromium)
The nickel content in SS 310 stainless steel is significantly higher than that of standard grades; consequently, even minor fluctuations in global nickel prices will directly impact the cost of the steel plates.
2. Thickness and Dimensions
The thicker the steel plate, the higher the rolling costs and the lower the material yield rate. Additionally, custom widths or lengths will incur extra processing fees.
3. Production Standards and Certifications
Steel plates produced in accordance with ASTM A240 or EN standards-and accompanied by EN 10204 3.1 certification-typically command a higher price, but they guarantee that product quality meets the required standards.
4. Surface Finish
Hot-rolled finishes (featuring a "black scale" surface) are lower in cost, whereas pickled or mechanically finished surfaces are more expensive but offer superior suitability for specific applications.
5. Processing Services
These include value-added services such as plasma cutting, flame cutting, and mechanical machining. Depending on the complexity of the processing required, these services may increase the total cost by 5% to 20%.
310S vs. 309S Stainless Steel Plate Prices
Due to its higher nickel (20% vs. 13%) and chromium (25% vs. 23%) content, the price of 310S stainless steel plate is typically higher than that of 309S; however, this composition also endows it with superior high-temperature oxidation resistance (effective up to 1150°C). For moderate-temperature environments (< 900°C), 309S represents a more cost-effective choice. The price of stainless steel plate typically fluctuates between $1,000 and over $2,000 per ton and is highly susceptible to fluctuations in the nickel market.
How can I get the best price for 310S?
Standard Dimensions: Whenever possible, opt for standard specifications specifically widths of 1500mm or 2000mm and lengths of 6000mm. Custom dimensions typically incur a "scrap surcharge."
Stock vs. Order: While purchasing from existing warehouse stock offers faster delivery, the price may be slightly higher than placing a direct "factory order" (which entails a production lead time of 30–50 days).
Verify Surcharges: Request a detailed breakdown of the current month's "alloy surcharge" from your supplier; this allows you to cross-reference it with prevailing nickel market trends to determine whether their quoted price is fair and reasonable.
