ウェルドネックフランジ – 迅速な配達

Originally developed to combat sea water corrosion, AL6XN has expanded its role as being good mid-range corrosion resistant alloy. AL6XN weld neck flanges are a low carbon, high purity, nitrogen-bearing “super-austenitic” stainless alloy. Also considered a 6Moly alloy, AL6XN flanges are similar in chemistry and capabilities to Alloy 926 and SMO 254. With a higher nickel and molybdenum content than Duplex 2205 およびスーパーデュプレックス 2507, it delivers better corrosion resistance while giving a more cost effective alternative to nickel super alloys like Inconel or Hastelloy in moderately corrosive conditions.

Corrosion Resistance• Moderate general corrosion resistance• Excellent chloride / salt water protection• Good performance in phosphoric acid• Moderate resistance to nitric acid

Chemical ResistanceIn chemical processes which utilize chlorides, such as paper mills and waste water, 応力腐食割れ (SCC) is a common culprit for 316L stainless failures. Duplex alloys will outlast environments that will cause SCC in 316 ステンレス, but for more severe low PH environments, weld neck flanges made from higher nickel content alloys like AL6XN will generally work better. For the most extreme situations, alloys with >45% nickel content like Hastelloy are often considered.

Outstanding Resistance to Salt WaterSeawater is where AL6XN weld neck flanges outperform so many alloys providing protection to stress corrosion cracking, pitting and crevice corrosion in a broad range of marine applications. AL6XN weld neck flanges contain a minimum of 6% molybdenum content and it is this addition of molybdenum that provides the greatest protection against pitting and crevice corrosion.

Mechanical PropertiesElectrical Resistivity: 535 Ohm-circ mil/ftUltimate Tensile Strength: 108 ksi0.2% Yield Strength: 53 ksiDensity: 0.291 lb/in 3

Chemistry• High molybdenum content provides enhanced corrosion protection in chloride environments.• Carbon helps to prevent sensitization during welding• Chromium enhances pitting and crevice corrosion resistance• The interstitial strengthening effect of nitrogen gives AL6XN weld neck flanges good high strength properties

AL6XN Applications• Desalination plants depend on AL6XN weld neck flanges for the salt water corrosion protection• Pulp bleaching equipment and piping • The power industry uses AL6XN weld neck flanges where salt water and chlorides are present such as steam surface condensers, supercritical, 高圧, feed water heaters, steam surface condensers, flue-gas desulfurization equipment and in nuclear power water piping • Offshore • Chemical Processing – processing tanks, vessels and pipes as well as plate and frame heat exchangers.
