Stainless Steel Sheet
UNS N08367/AL-6XN/25-6HN Stainless Steel
UNS N08367 is a type of high Molybdenum containing super austenitic
stainless steel that has nickel as the base metal. This alloy has
nickel-chromium-iron as the primary constituents. By varying the
other elements, it can be designed to resist attacks from specific
chemical reagents. This alloy exhibits high strength even at high
temperatures. 6% Mo, high Ni, and N alloyed austenitic grade with
extremely high resistance to both uniform and localized corrosion.
Commonly used in applications to withstand chlorinated sea water
and also used in flue gas cleaning.

UNS N08367 is also known as super-austenitic stainless steel. This
alloy contains a higher content of Molybdenum and Nitrogen (so it
is also called 6% Mo Super Austenitic Stainless Alloy, AL-6XN, NAS
254NM, INCOLOY alloy 25-6HN, F62). These additions enhance the
thermal stability and corrosion resistance of the alloy. Among
super austenitic stainless steels, UNS N08367 offers a higher
degree of corrosion resistance and strength.

Machinability
Machining of UNS N08367 should be done at a slightly lower speed
when compared to 316 stainless steel, as it has high strength.
Welding
UNS N08367 can be welded by shielded metal arc welding, gas
tungsten arc welding, submerged arc welding, plasma arc welding and
gas metal arc welding. The filler metal and electrodes are usually
made of INCONEL alloy.
Hot-working
UNS N08367 can be hot worked at temperature ranges of 982-1232°C
(1800-2250°F).
Annealing
UNS N08367 should be annealed at temperatures greater than 1121°C
(2050°F).
