AL6XN Stainless Steel Tube is a low carbon, high nickel, molybdenum-containing "super austenitic" low carbon stainless steel with strong corrosion resistance, including pitting, crevice corrosion and stress corrosion cracking. N08367 also has strong resistance to chloride corrosion, which is very suitable for use in marine environments, desalination plants and other environments. Alloy Al6xn also has high strength and toughness, 50% stronger than stainless steel. And excellent heat resistance, high temperature resistance up to 800° F.
