N08367 Super Austenitic Stainless Steel Pipe Al-6XN 1.4529 Incoloy25-6hn

ASTM A312, ASTM A213 ,N08367 Al-6XN 1.4529 Incoloy25-6hn NAS 255NM Super Austenitic Stainless Steel Pipe and Tube

When the pitting corrosion resistance equivalent value of chromium-nickel austenitic stainless steel (PREN = [Cr] +3.3 [Mo] +16 [N]) ≥40%, it can be called super austenitic stainless steel.

Super austenitic stainless steel is mainly used to solve the lack of pitting and crevice corrosion resistance and poor thermal stability of the original high-molybdenum (> 4%) chromium-nickel austenitic stainless steel under the severe corrosion conditions containing Cl-. And developed.
