In recent years, the stainless steel market has been heavily influenced by volatility in nickel and molybdenum prices. Nickel, as one of the key alloying elements in duplex and super duplex stainless steels, directly impacts the cost structure of grades like UNS S32750 (2507). When nickel prices fluctuate due to global supply constraints, energy costs, or geopolitical factors, buyers often see immediate price adjustments in high-performance stainless steel products. For procurement teams, this makes understanding the true cost drivers behind UNS S32750 stainless steel pipe price per kg essential for budgeting and long-term contract planning.
What is UNS S32750 Stainless Steel Pipe?
UNS S32750 commonly referred to as "Super Duplex 2507" is a high-alloy stainless steel that exhibits exceptional resistance to chloride pitting and crevice corrosion. Offering a long service life in harsh environments, it is widely utilized in fields such as offshore oil and gas extraction, seawater processing systems, chemical plants, and heat exchangers.
UNS S32750 Stainless Steel Pipe Price per kg (Latest 2026)
As of April–May 2026, the international market price of UNS S32750 (Super Duplex 2507) stainless steel pipes typically ranges from USD 8.50 to 12.50 per kg. In the Chinese market, depending on specifications and order volume, the price is generally around 55 to 95 RMB per kg. Prices fluctuate with market demand, and for smaller diameters, special customized products, or thicker wall pipes, the unit price may be relatively higher.
Analysis of UNS S32750 Stainless Steel Pipe Price Trends: January–May 2026
Price Trend Analysis:
China FOB Price: Rose steadily from $6.00/kg in January to $7.00/kg in May, representing a cumulative increase of 16.7%.
U.S. Market Price: Rose from $8.00/kg in January to $9.30/kg in May, representing a cumulative increase of 16.25%.
The trends in both markets were largely synchronized, exhibiting a pattern of continuous upward growth.
Key Factors That Affect UNS S32750 Pipe Price per kg
Nickel and molybdenum represent a significant portion of production cost. Even small changes in LME nickel prices can directly impact final pipe pricing.
LME Nickel Price Analysis (January-May 2026)
Price Trend Summary
January-February: LME nickel price remained stable at around $19,500/ton, supported by Indonesian supply restriction expectations
March: Significant price drop to $16,984/ton, representing a 12.8% decline from February levels
April: Strong rebound with 7.17% monthly increase, reaching $18,640/ton
May: Continued upward momentum, closing at $19,115/ton, representing a 2.5% increase from April
Why UNS S32750 is More Expensive than Duplex 2205 or 316L?
The reason the price of UNS S32750 (commonly referred to as "Super Duplex 2507") is higher than that of Duplex 2205 or 316L stainless steel is primarily attributed to its higher alloy content. Generally speaking, the price per ton of Super Duplex 2507 is 20% to 40% higher than that of Duplex 2205; Duplex 2205 itself typically commands a higher price than 316L, although the price of 316L is heavily influenced by fluctuations in nickel prices and, consequently, tends to exhibit greater price volatility.
Procurement Advice for Buyers
To optimize purchasing cost and reduce risk:
Lock long-term contracts when nickel prices are low
Clearly define specifications to avoid over-engineering
Choose welded vs seamless based on actual pressure requirements
Consolidate order volumes to reduce per kg pricing
Work with certified suppliers for stable quality and documentation (EN 10204 3.1/3.2)
For critical energy projects or maintenance operations, Gnee offers priority production scheduling services. Gnee provides 100% Mill Test Certificates (MTCs) in compliance with the EN 10204 3.1 standard. Upon customer request, we can also arrange for Third-Party Inspection (TPI) services from agencies such as SGS, BV, or Lloyd's.
Lead Times:
Stock Products: 7–10 days. Standard-specification pipes, fittings, and bars can typically be arranged for immediate shipment following final inspection and cleaning.
Production Orders (Custom Manufacturing): 30–45 days. This applies to products such as large-diameter welded pipes, thick-walled seamless pipes, or specialized U-bend heat exchanger tubes.

Packaging and Shipping
Bundling: For pipes with small outer diameters, a hexagonal bundling method is employed; the bundles are secured using steel bands and plastic lifting slings to facilitate hoisting operations.
Wooden Crate Packaging: Products such as U-bent tubes, heat exchanger tubes, and pipe fittings are strictly packed in wooden crates to prevent bending, deformation, or surface scratches.
Marking: Each pipe is clearly stenciled with its furnace number, material grade, dimensions, and applicable standards to ensure full traceability throughout the entire process.
