What is the price of stainless steel Duplex 2205 pipe?
Prices for Duplex 2205 stainless steel pipes vary significantly based on dimensions, thickness, and supplier, generally ranging from $1,000 to $3,000 per ton for standard seamless and welded varieties. Specific pricing data indicates a market range of $5.00 to $7.00 per kilogram for pipes, with individual unit prices fluctuating from $34.53 to $2,817.11 depending on size (e.g., 2" Sch 80 vs. large OD configurations).
What is the price of SS 316 pipe per kg?
As of early 2026, the benchmark price for 316L seamless steel pipe was $4.29/kg (ex-works price, excluding excise tax), while the average selling price of seamless steel pipe ranged from $2.20/kg to $4.18/kg. ERW welded steel pipe of certain sizes was priced between $2.31/kg and $2.75/kg, with excessively large or small sizes typically commanding higher prices.
Which is better, 2205 or 316 stainless steel pipe?
2205 Duplex Stainless Steel is generally superior for demanding industrial applications due to its nearly double the strength and significantly higher corrosion resistance compared to 316 stainless steel, particularly in chloride-rich environments like seawater. However, 316 stainless steel remains the better choice for applications requiring easier fabrication, better cold forming, and higher temperature resistance (up to 800°C) where cost is a primary constraint.
316 ss pipe vs duplex 2205 pipe：Chemical Composition (%)
The higher Chromium, Molybdenum, and addition of Nitrogen give Duplex 2205 its superior properties.
| Element | AISI 316L | Duplex 2205 |
| Chromium (Cr) | 16.0 – 18.0 | 22.0 – 23.0 |
| Nickel (Ni) | 10.0 – 14.0 | 4.5 – 6.5 |
| Molybdenum (Mo) | 2.0 – 3.0 | 3.0 – 3.5 |
| Nitrogen (N) | 0.10 max | 0.14 – 0.20 (Strengthener) |
| Carbon (C) | 0.03 max | 0.03 max |
316 ss pipe vs duplex 2205 pipe：Mechanical Properties
Duplex 2205 has a significantly higher yield strength, allowing for wall thickness reduction (weight saving) in piping systems.
| Property | AISI 316L (Annealed) | Duplex 2205 (Annealed) |
| Yield Strength 0.2% (MPa) | ≥ 170 | ≥ 450 (Nearly 2.5x higher) |
| Tensile Strength (MPa) | ≥ 485 | ≥ 620 |
| Elongation (%) | ≥ 40% | ≥ 25% |
| Hardness (Brinell) | ~160 HB | ~290 HB (Superior wear resistance) |
Corrosion Resistance : 316 SS vs Duplex 2205
| Parameter | 316 Stainless Steel | Duplex 2205 | Description |
|---|---|---|---|
| PREN Value | ~25 | ~36 | Pitting Resistance Equivalent Number; higher values indicate stronger resistance to pitting corrosion |
| CPT (°C) | ~25°C | >60°C | Critical Pitting Temperature; higher values mean better resistance to chloride-induced pitting |
| CCCT (°C) | ~15°C | ~35°C | Critical Crevice Corrosion Temperature |
| SCC Resistance Index | 35 | 95 | Stress Corrosion Cracking resistance; 2205 is significantly superior to 316 |
316 ss pipe vs duplex 2205 pipe：Application
| 316/316L Pipe | Food/beverage, pharmaceuticals, low-pressure chemical lines, architectural trimming. |
| Duplex 2205 Pipe | Oil & gas subsea piping, chemical tankers, desalination plants, high-pressure heat exchangers. |
What is the difference between Duplex 2205 and ss304?
Duplex 2205 is a high-performance duplex (ferritic-austenitic) stainless steel with a yield strength approximately twice that of standard austenitic SS304, offering superior corrosion resistance, but at a significantly higher cost (approximately 60-80% more). While SS304 is suitable for general, food-grade, or moderately corrosive applications, SS2205 is specifically designed for harsh, heavy-duty industrial environments such as chemical processing and marine environments.
