2507 Duplex Stainless Steel Pipe Price List

Looking for a 2507 duplex stainless steel pipe price list for an oil and gas, offshore, desalination, or chemical processing project? The price of Super Duplex 2507 pipe depends on the pipe diameter, wall thickness, seamless or welded manufacturing process, order quantity, inspection requirements, and current nickel and molybdenum costs.
This guide provides a 2026 price reference, explains how to calculate pipe costs, compares the factors that affect supplier quotations, and shows buyers how to purchase 2507 stainless steel pipes from GNEE.

 

Why does the price of 2507 steel pipe fluctuate so significantly?

Nickel and molybdenum are its core alloying elements; changes in metal prices on the London Metal Exchange (LME) directly affect alloy surcharges. Furthermore, lead times, the scope of inspection, and certification levels also influence the final price.

 

How much does 2507 duplex stainless steel pipe cost per kg?

The price varies by dimensions, manufacturing method, quantity, and inspection scope. A published Chinese domestic market reference for a reported Ø219 × 4 mm 2507 pipe was RMB 46,200/ton, equivalent to RMB 46.20/kg, on October 19, 2026. This is a historical market reference for that reported specification, not a guaranteed current export price.

How to Calculate 2507 Stainless Steel Pipe Price per Meter?

When comparing 2507 duplex stainless steel pipe prices, buyers should calculate the theoretical pipe weight per meter before comparing supplier quotations. Pipe weight depends mainly on the outside diameter (OD), wall thickness (WT), and material density. Once the estimated weight is known, the price per meter can be calculated from the quoted price per kilogram.

2507 Stainless Steel Pipe Weight Formula

For a round pipe, the approximate theoretical weight is: Weight (kg/m) = 0.02450 × WT × (OD − WT)

Where:

OD = outside diameter in mm

WT = wall thickness in mm

0.02450 = approximate calculation constant based on a density of 7.8 g/cm³

Weight = theoretical weight in kg per meter

This formula is suitable for preliminary cost estimation. Actual weight may vary according to the material density, dimensional tolerances, manufacturing method, and agreed commercial weighing basis.

 

Example: Calculate the Weight of 2507 Pipe

Assume the required Super Duplex 2507 pipe has the following dimensions:

Parameter	Value
Grade	UNS S32750 / 2507
Outside diameter	219 mm
Wall thickness	4 mm
Pipe length	6 m
Illustrative material price	US$10/kg

Step 1: Calculate the theoretical weight per meter.

Weight = 0.02450 × 4 × (219 − 4)

Weight = 21.07 kg/m

Step 2: Calculate the theoretical weight of one 6-meter pipe.

21.07 × 6 = 126.42 kg per pipe

Step 3: Calculate the estimated material price per meter.

21.07 kg/m × US$10/kg = US$210.70/m

Step 4: Calculate the estimated material price per 6-meter pipe.

126.42 kg × US$10/kg = US$1,264.20 per pipe

Note: US$10/kg is an illustrative price used to explain the calculation, not a confirmed market quotation or GNEE offer. The example assumes theoretical weight and excludes packaging, inspection surcharges, freight, taxes, and other applicable charges.

FAQ

What is the difference between 2507 duplex steel pipe and 2205 duplex steel pipe?
2507 (S32750) has a Pitting Resistance Equivalent Number (PREN) of ≥40 and contains higher proportions of chromium (Cr), molybdenum (Mo), and nitrogen (N). It is capable of withstanding environments with higher chloride concentrations, seawater immersion, and sulfur-containing (sour) service conditions. 2205 (S32205) has a PREN of approximately 34–38; it is more cost-effective but is only suitable for environments with lower chloride levels. In offshore facilities or saltwater injection pipelines, 2205 cannot be used as a substitute for 2507.

 

Is 2507 stainless steel more expensive than 2205?
Generally, yes. 2507 contains higher levels of key alloying elements, including chromium and molybdenum, and is designed for more demanding corrosion environments. The actual price difference depends on the product form, dimensions, supply conditions, and current alloy costs.

 

What is the maximum operating temperature for 2507 duplex steel pipe?
Best practice suggests keeping it below 300°C. Long-term operation at temperatures above 320°C can lead to the precipitation of the "sigma phase" (σ phase) within the material, which causes a sharp decline in both toughness and corrosion resistance.

 

What is the lead time for 2507 seamless steel pipe?
For standard stock specifications, the lead time is 7–10 business days. For custom thick-walled pipes, orders with special tolerance requirements, or those requiring third-party inspection (3.2 certification), the lead time is 25–40 days, depending on the steel mill's production schedule.
