Virami Steel Hub is a leading manufacturer, supplier, stockist, and exporter of AL-6XN Round Bars in Mumbai, India. We provide high-quality AL-6XN alloy round bars to clients across India and worldwide, serving industries such as oil & gas, marine, chemical processing, desalination, power generation, pulp & paper, and offshore engineering.
AL-6XN is a super austenitic stainless steel known for its exceptional resistance to chloride-induced corrosion, superior strength, and excellent fabrication properties. It is widely used in aggressive environments where conventional stainless steels cannot perform reliably.Our AL-6XN round bars are supplied in various diameters, finishes, and specifications, meeting global industrial standards and ensuring consistent quality and performance.
AL-6XN (UNS N08367) is a high-performance nitrogen-bearing super austenitic stainless steel containing approximately 6% molybdenum. The alloy is designed to provide outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments.
AL-6XN Round Bars are solid cylindrical bars manufactured from this advanced alloy, offering:
Due to its enhanced chemical composition, AL-6XN is commonly used in highly corrosive industrial systems.
The outstanding performance of AL-6XN round bars is due to its carefully balanced alloying elements:
| Element | Composition (%) |
|---|---|
| Chromium (Cr) | 20.0 – 22.0 |
| Nickel (Ni) | 23.5 – 25.5 |
| Molybdenum (Mo) | 6.0 – 7.0 |
| Nitrogen (N) | 0.18 – 0.25 |
| Manganese (Mn) | 2.0 max |
| Silicon (Si) | 1.0 max |
| Copper (Cu) | 0.75 max |
| Carbon (C) | 0.03 max |
| Phosphorus (P) | 0.04 max |
| Sulfur (S) | 0.03 max |
| Iron (Fe) | Balance |
Role of Alloying Elements
This composition gives AL-6XN an excellent Pitting Resistance Equivalent Number (PREN), making it highly suitable for chloride-rich environments.
AL-6XN offers high strength combined with excellent ductility and toughness.
The nitrogen addition significantly enhances yield strength without compromising ductility.
One of the most important features of AL-6XN round bars is their exceptional corrosion resistance.
Pitting & Crevice Corrosion: The high molybdenum and nitrogen content provide outstanding resistance to chloride-induced pitting and crevice corrosion.
Stress Corrosion Cracking (SCC)AL-6XN offers excellent resistance to stress corrosion cracking in chloride environments, making it ideal for offshore and marine applications.
Seawater Resistance: The alloy performs exceptionally well in seawater and brackish water conditions.
Acid Resistance: It demonstrates strong resistance to sulfuric acid, phosphoric acid, nitric acid, and various chemical processing environments.
AL-6XN is typically supplied in the solution annealed condition.
Solution Annealing:
This process ensures maximum corrosion resistance and optimal structural stability.
Due to its high alloy content, AL-6XN is tougher to machine than standard stainless steels.
Recommended machining practices:
With proper tooling, precision components can be manufactured efficiently.
AL-6XN offers good weldability when proper procedures are followed.
It can also be formed, rolled, and fabricated using conventional stainless steel techniques.
