SMO 254 WN Flange Producenter ASTM A182 SMO 254 Slip On Flange
316 er medlem af 18\/8 kromnikkelfamilien af austenitiske rustfrie stål, med tilsætning af 2% molybdæn for forbedret korrosionsbestandighed, især over for lokal korrosion i kloridholdige miljøer.
AL-6XN Stainless Steel Flange is made of a super-austenitic metal designed to resist crevice corrosion, pitting, chloride-induced corrosion, and stress corrosion cracking. AL-6XN Stainless Steel Flange can also withstand alkaline and salt solutions, protecting against metallic contamination of product and preventing rapid degradation of the fluid transfer system. The chromium, molybdenum and nitrogen improve the resistance to pitting corrosion while the nickel and molybdenum increase the resistance to chloride-stress corrosion. Nitrogenet øger trækstyrken til et højere niveau sammenlignet med de almindelige austenitiske rustfrie stål. The alloy has good cold formability, which makes it easy for drawing, bending, pressing or any other forming process required to produce fabricated items. Bøjning over en skarp hanmatrice kan dog forårsage revner i materialet.
