AL-6XN |
UNS N08367 |
GENERAL PROPERTIES
AL-6XN is low carbon, nitrogen bearing super austenitic stainless steel. The alloy was designed to be a seawater resistant material and has been found to be resistant to a broad range of corrosive environments. Due to the alloy’s corrosion resistance and high strength, AL-6XN is a better choice than conventional duplex stainless alloy and more cost effective nickel-base alloys.
RESISTANCE TO CORROSION
Known as a "super austenitic" stainless, this alloy combines high strength and good fabricability with excellent corrosion and pitting resistance to a wide variety of media.

WELDING
All methods except oxyacetylene welding have been successfully used with this alloy. While a filler metal of type 316 stainless may be sufficient for some applications, it is preferable to employ a higher alloy such as 625, or C-276 for maximum performance.
HEAT TREATMENT
If necessary, AL-6XN alloy is annealed after heavy cold work 2050-2150°F (1121-1177C), water quench. Slow cooling is not recommended, as this would reduce the alloy’s corrosion resistance.
