Introduction to Alloy 926
Alloy 926 is a super-austenitic stainless steel enhanced with high molybdenum (6.0-7.0%), nitrogen (0.15-0.25%), and nickel (24-26%). Designed for extreme corrosive environments, it bridges the gap between standard austenitic steels (e.g., 316L) and high-cost nickel alloys.
Key Features
- Exceptional corrosion resistance in chloride-rich media (e.g., seawater, acids)
- High strength and ductility due to nitrogen strengthening
- Applications span marine engineering, chemical processing, and pollution control systems
Key Parameters & Properties
Chemical Composition
| Element | Composition (%) | Role |
|---|---|---|
| Ni | 24.0-26.0 | Stabilizes austenite; boosts acid resistance |
| Cr | 19.0-21.0 | Forms passive oxide layer |
| Mo | 6.0-7.0 | Enhances pitting/crevice corrosion resistance |
| N | 0.15-0.25 | Increases strength; improves localized corrosion resistance |
| Cu | 0.5-1.5 | Resists sulfuric acid |
| Fe | Balance | Base material |
Minor elements: C ≤0.02%, Mn ≤2.0%, Si ≤0.5%
Physical & Mechanical Properties
| Property | Value |
|---|---|
| Density | 8.1 g/cm³ |
| Melting Point | 1320-1390 °C |
| Tensile Strength (Rm) | ≥650 MPa |
| Yield Strength (RP0.2) | ≥295 MPa |
| Elongation (A5%) | ≥35% |
| Hardness (RB) | ≤86 |
Data at room temperature (after solution annealing)
Corrosion Resistance Highlights
| Environment | Performance |
|---|---|
| Seawater/Chlorides | Resists pitting/crevice corrosion (PREN >40) |
| Acids | Excellent in H2SO4, H3PO4, organic acids |
| Stress Corrosion Cracking (SCC) | Resists Cl--induced SCC |
Validated in FGD systems (Cl- 10,000-70,000 ppm, 50-68°C)
Standards & Certifications
| Standard Type | Applicable Codes |
|---|---|
| Material Standards | ASTM B168 (plate/sheet), ASTM B906 (strip), EN 1.4529, UNS N08926 |
| Fabrication Certifications | ASME Sec. VIII, VdTÜV (196-400°C) |
| Welding Fillers | ERNiCrMo-3 (Alloy 625), ERNiCrMo-12 |
Typical Dimensions & Forms
926 stainless steel strip is supplied in cold-rolled, solution-annealed, and descaled conditions.
| Parameter | Range |
|---|---|
| Thickness | 0.1-5.0 mm |
| Width | 10-2000 mm |
| Surface Finish | No. 1 (annealed), 2B (smooth), BA (bright annealed) |
Other forms: Sheets, coils, foil (custom widths/lengths available)
Advantages of Alloy 926 Strip
- Corrosion Superiority: Outperforms 904L, 316L, and duplex steels in chloride/sulfide media
- Cost Efficiency: Economical alternative to nickel alloys (e.g., Hastelloy) in marine/chemical systems
- Mechanical Robustness: 35% elongation enables deep drawing; high strength allows thinner sections
- Weldability: Maintains corrosion resistance post-welding with proper fillers
Applications
| Industry | Specific Use Cases |
|---|---|
| Marine Engineering | Seawater piping, desalination plants (RO membranes), shipboard systems |
| Pollution Control | FGD scrubbers, ducting, chimneys |
| Chemical Processing | Heat exchangers, reactors, acid storage tanks |
| Oil & Gas | Polished rods for corrosive wells, subsea components |
| Energy | Condensers using wastewater cooling |

Suppliers & Notes
- Key Suppliers: Shanghai Baoyuan Steel, Shanghai Weili Metal
- Handling Tips:
- Avoid sulfur contamination during heat treatment (max 0.1% in fuel)
- Cold working >15% requires re-solution annealing
For detailed specifications or testing reports, consult manufacturer datasheets or standards (e.g., ASTM B168, EN 1.4529).
