UNS N08367, commonly known as AL-6XN stainless steel, is a high-performance super austenitic alloy designed for exceptional corrosion resistance in chloride-rich environments.
Due to its high molybdenum and nitrogen content, AL-6XN offers superior performance compared to traditional stainless steels such as 316L and 904L.
This article covers its properties, composition, and applications, helping you choose the right material for demanding environments.
What is UNS N08367 (AL-6XN)?
AL-6XN (UNS N08367 / EN 1.4529) is a super austenitic stainless steel developed for resistance to pitting, crevice corrosion, and stress corrosion cracking.
It is especially suitable for harsh environments such as seawater systems and chemical processing plants.
Key Features
- Excellent resistance to chloride corrosion
- High strength and durability
- Good weldability
- Long service life in aggressive conditions
AL-6XN is widely recognized for its outstanding corrosion resistance, particularly in chloride-containing environments.
Corrosion Resistance Highlights
- Excellent resistance to pitting corrosion
- Strong resistance to crevice corrosion
- High resistance to stress corrosion cracking (SCC)
- Performs well in seawater and brine
Compared to 316L, AL-6XN offers significantly improved durability in harsh conditions.
AL-6XN vs 904L vs 254SMO
| Feature | AL-6XN | 904L | 254SMO |
|---|---|---|---|
| Corrosion Resistance | Excellent | Good | Best |
| Pitting Resistance | High | Medium | Very High |
| Cost | Medium-High | Lower | Highest |
Conclusion
- Choose AL-6XN → balanced performance
- Choose 254SMO → extreme environments
- Choose 904L → cost-effective option
Why Choose AL-6XN?
- Better than 316L in chloride environments
- High PREN value (>40)
- Longer service life
- Reduced maintenance cost
