Temperature Stability
AL-6XN alloy is metallurgically stable to 1000 °F (540 °C) and has
no phase transformation even after extensive deformation. When
exposed to temperatures in the range of 1200-1800° F the
opportunity for chi phase formations exists. Chi phase, a
chromium-iron-molybdenum compound (sometimes incorrectly referred
to as sigma phase), forms along the grain boundaries depleting the
area of molybdenum and chromium reducing the corrosion resistance
of the material. In order to help combat chi phase formation,
nitrogen was added to the AL-6XN alloy to minimize this formation,
improving corrosion resistance and increasing strength over a broad
range of temperatures, while maintaining the good formability of
austenitic stainless steel.
The high strength and corrosion resistance of the AL-6XN alloy make
it a better choice than the conventional duplex stainless steels
and a cost effective alternative to more expensive nickel-based
alloys in applications where excellent formability, weldability,
strength and corrosion resistance are essential. It is a cost
effective alternative to less expensive stainless steels that do
not have the strength or corrosion resistance to maximize life
cycles.
AL-6XN alloy has exceptional resistance to chloride corrosion,
pitting, crevice corrosion, stress corrosion cracking, and
excellent general corrosion resistance to various acid, alkalis and
salt solutions.
AL-6XN alloy is identified by the Unified Numbering System (UNS)
designation of N08367. AL-6XN alloy is an austenitic stainless
steel alloy with high nickel, molybdenum, and nitrogen content.
AL-6XN alloy has a face-centered cubic crystal structure similar to
other austenitic stainless steels. The alloy is non-magnetic and
its magnetic permeability remains low even after severe cold
forming.
