Stainless Steel AL-6XN®
ASTM B 688, B 691, B 675 / 676
B 462, B 366, B 564, B 804
UNS N08367
The AL-6XN® alloy is a superaustenitic stainless steel which was developed by Allegheny Ludlum Corporation. It is a high molybdenum superaustenitic stainless steel developed to handle oxidizing and acidic chloride solutions. The higher levels of chromium, molybdenum, and nitrogen provide a far greater resistance to chloride pitting, crevice corrosion, and stress-corrosion cracking than exhibited by the 300 series stainless steels.
Mega Mex supplies AL-6XN® in the form of plates, sheets, strips, bar, wire, pipe, fittings, welding wire, welding electrode.
Typical applications are:
- Pulp bleaching equipment and piping
- Sea water heat exchangers
- Chemical process tanks and pipelines
- Brewery equipment
- Reverse osmosis desalination equipment and pumps
- Offshore oil and gas process systems
- Food processing equipment
- Pharmaceutical processing pipes and vessels
- Tall oil distillation columns
Chemical Composition:
| Element | Avg. Nominal % |

| Sulfur | Nil - 0.03 |
| Copper | Nil - 0.75 |
| Iron | Balance |
Fabrication with AL-6XN®
AL-6XN® is readily fabricated by using standard austenitic stainless steel practices. In comparison to carbon steel, stainless steels are tougher and tend to work harden rapidly.
