Alloy 20 Flange, UNS N08020, is also known as 20Cb-3, CN7M(castings), or DIN 2.4660. It has exceptional corrosion resistance to sulfuric acid and has good performance in handling pitting corrosion, crevice corrosion, intergranular corrosion, and stress-cracking corrosion. Meanwhile, its cost is comparatively lower than other corrosion-resistant alloys. Therefore, Alloy 20 can be used in a variety of applications including petrochemical industry, chemical processing, food & pharmaceutical industries, and power plant, etc.
Alloy 20 Flange is used in a variety of industries, including chemical processing, petrochemical and refining, marine, pharmaceutical and food processing. End use applications include storage tanks, mixing tanks, agitators, pump and valve parts, food processing equipment, fasteners and fittings. Applications are limited to a maximum temperature of 1000°F per ASME. It is also important to determine if the necessary corrosion resistance can be achieved within the given environment.
