In 1991, CSI learned that AL-6XN alloy could provide superior corrosion resistance where traditional 316L stainless steel components were inadequate. Since that time, CSI has developed a complete line of sanitary fittings and tubing in AL-6XN alloy for the processing industries.
AL-6XN alloy is a super-austenitic metal designed to resist crevice corrosion, pitting, chloride-induced corrosion, and stress corrosion cracking. It can also withstand alkaline and salt solutions, protecting against metallic contamination of product and preventing rapid degradation of the fluid transfer system.
Originally developed for seawater applications, AL-6XN is used successfully in food, pharmaceutical, and biopharmaceutical processes. The "superalloy" resists the attack of corrosive food and beverage products such as: sports drinks, ketchup, soy and barbecue sauce, and salsa. It is also beneficial in fine chemical, cosmetic and pharmaceutical (cosmeceutical), brewery, desalination, semi-conductor, aerospace, biopharm, pulp and paper, and gas handling applications.
