If you are looking for a high-strength, corrosion-resistant stainless steel material for demanding applications, duplex stainless steel 2205 is an excellent choice. Understanding the price per kg of 2205 duplex stainless steel and what affects it is crucial for procurement teams and engineers.
What is Duplex Stainless Steel 2205?
Duplex stainless steel 2205 (UNS S31803/S32205) is a nitrogen-strengthened duplex stainless steel that combines the advantages of austenitic and ferritic stainless steels. It has excellent resistance to chloride stress corrosion cracking, its yield strength is twice that of 304/316 stainless steel, and it has good weldability and toughness.
Duplex Stainless Steel 2205 Price per kg (2025 Reference)
| Product Form | Surface Finish | Price Range (USD/kg) |
|---|---|---|
| 2205 Stainless Steel Plate | No.1 / 2B | $4.50 – $6.00 |
| 2205 Round Bar | Peeled / Bright | $5.00 – $6.80 |
| 2205 Seamless Pipe | Annealed | $5.50 – $7.50 |
| 2205 Welded Pipe | Pickled | $4.20 – $6.00 |
| 2205 Coil/Strip | 2B / BA | $4.00 – $5.80 |
Note: The price of 2205 stainless steel mainly depends on the cost of raw materials such as nickel, chromium, molybdenum, product specifications, processing technology, and market supply and demand. If you have project needs, you can contact GNEE in time to get a competitive price!
Duplex 2205 Weight Calculation Formula
To estimate the total weight and cost of your Duplex 2205 material, use the following formulas:
✅1. Plate / Sheet Weight (kg)
Weight = Length (mm) × Width (mm) × Thickness (mm) × ρ / 1,000,000
ρ (Density of 2205) ≈ 7.80 g/cm³ or 7.80 × 10⁻³ g/mm³
Example: A 6mm thick 2205 plate (1000mm × 2000mm)
Weight = 1000 × 2000 × 6 × 7.80 / 1,000,000 = 93.6 kg
✅ 2. Round Bar Weight (kg/m)
Weight = (π × D² / 4) × ρ × 1000
D = Diameter in mm
ρ ≈ 0.00780 g/mm³
✅ 3. Pipe Weight (kg/m)
Weight = 0.02466 × (OD - WT) × WT
OD = Outer Diameter (mm)
WT = Wall Thickness (mm)
These formulas help estimate total material weight and pricing based on kg rate.If you have any questions, please contact us in time!
