Material Description:
Al-6XN (UNS N08367) is a super austenitic stainless steel with
excellent resistance to chloride ion pitting and crevice corrosion.
As a corrosion-resistant alloy with good cost performance, its
comprehensive corrosion resistance is relatively higher than that
of 316L It is a great leap forward, and its corrosion resistance is
close to other corrosion-resistant nickel-based alloys such as
C-276, and the cost advantage is obvious. Because of the
significant nitrogen content added to the alloy, the Al-6XN
material has higher tensile strength than conventional austenitic
stainless steels (such as 304, 316, 317, etc.), while maintaining
excellent material toughness and impact strength. ASME Standard The
allowable stress value specified in the specification, Al-6XN is
40% higher than 316L and nearly double that of copper-nickel alloy.
Typical conditions: 60% sulfuric acid, below 80 ° C, annual
corrosion rate <0.1mm Supporting welding materials and welding
process: AWS A5.14 welding wire ERNiCrMo-3 or AWS A5.11 welding rod
ENiCrMo-3 is recommended for alloy welding. Welcome to call for
