Chemical Composition of Duplex Pipe Fittings
The mix of austenite and ferrite phases is what makes Duplex 2205 stronger and more corrosion-resistant than 316L. S32205 has higher minimum Nitrogen and Chromium than S31803, giving it better PREN and sour-service performance - why most new Aramco projects now choose S32205.
Mechanical Properties of Duplex 2205 Pipe Fittings
Duplex Stainless Steel's two-phase structure gives it about double the strength of 316L at a similar cost, so it needs thinner walls. That's why Saudi Aramco and offshore engineers specify UNS S32205 wherever weight savings and high-pressure chloride service both matter.
| Property | UNS S31803 | UNS S32205 |
|---|---|---|
| Tensile Strength (Min) | 620 MPa | 655 MPa |
| Yield Strength 0.2% (Min) | 450 MPa | 450 MPa |
| Elongation (Min) | 25% | 25% |
| Hardness (Max) | 290 HV10 | 290 HV10 |
| Charpy Impact (0°C) | ≥ 100 J avg | ≥ 100 J avg |
| Density | 7.82 g/cm³ | 7.82 g/cm³ |
| Modulus of Elasticity | 200 GPa | 200 GPa |
| PREN (Min) | ≥ 35 | ≥ 35 |
* PREN = %Cr + 3.3×%Mo + 16×%N. Higher PREN = better resistance to pitting in chloride service. All values per ASTM A815 / ASME SA 815. 316L reference only - not interchangeable in Duplex piping classes.
Duplex Pipe Fittings Material Equivalent Grade
When ordering ASTM A815 UNS S31803 or S32205 Duplex fittings for Saudi Aramco, SABIC, or other project specs, check the EN, DIN, and NORSOK equivalents to keep documentation compliant. All stock through pipingmaterial.sa is dual-certified where available.

What Procurement Needs to Know Before Buying Duplex Steel Buttweld Fittings ?
Sourcing Duplex Pipe Fittings for a Saudi Aramco project isn't a simple purchase. The approved vendor list , material spec (SAMSS), and inspection class decide which mills, grades, and documents are acceptable. Miss one, and your MR gets rejected at the gate.

Which Grade Do Saudi Projects Specify S31803 vs S32205?
This is the most common question from Saudi procurement engineers ordering Duplex Pipe Fittings. The answer depends on your piping class, the project year, and whether you're working with Saudi Aramco, SABIC, or an EPC following NORSOK.
Duplex Fittings Price Factors in Saudi Arabia
Duplex 2205 Fittings suppliers in Riyadh and Dammam price material based on four key factors. Knowing these helps your team qualify quotes accurately and avoid comparing mismatched offers.
Grade - S31803 vs S32205
- S32205 costs 3-7% more than S31803
- Dual-certified material sits 2-4% below S32205
- Confirm piping class before RFQ to avoid re-pricing
Nickel & Molybdenum Spot Price
- Duplex 2205 carries 4.5-6.5% Ni, 3% Mo
- 10% Ni spot rise lifts fitting price 4-6%
- Lock pricing at RFQ approval for jobs over 4 weeks
Size, Wall & Fitting Type
- 16" SCH 40 elbow costs 8-12× a 2" equivalent
- Returns & crosses carry 15-25% premium over elbows
- Weight, not size alone, drives the price jump
Certification & Inspection Level
- IC-1 inspection with BV/SGS adds 5-10% to cost
- NACE MR0175, ferrite & RT testing add further cost
- Request itemised certification costs upfront
Applications of ASTM A815 WP-S UNS S31803 Elbow
From offshore wellheads in the Arabian Gulf to seawater cooling systems in Yanbu and desalination plants on the Red Sea coast, Duplex Stainless Steel Pipe Fittings handle the Kingdom's toughest corrosive, high-pressure jobs.
Why Duplex SS Fittings Outperform 316L in Saudi Environments ?
Pitting Resistance
PREN ≥ 35 vs 316L's ≤ 25 - holds up far longer in Gulf seawater.
Higher Yield Strength
Roughly double 316L's strength - thinner walls, lighter piping, lower support cost.
Proven Track Record
Field-proven on Khurais, Shaybah, and Manifa offshore projects.
No Post-Weld Heat Treatment
Low carbon content prevents sensitisation - skip PWHT entirely.
NACE MR0175 Certified
Mandatory clearance for any H2S hydrocarbon service in KSA.
