Description
ALLOY - 20
Nickel is enough to protect it from chloride-ion stress corrosion cracking, so it won't break. The nickel, with the molybdenum and copper, is also very resistant to chemicals that break down metals, like sulfuric acid and sulfuric acid. Molybdenum helps keep corrosion at bay in pits and crevices by preventing it from taking place. Oxidizing environments can't damage the alloy because there is a lot of chromium in it. This makes the metal more durable when it is heated because the titanium and aluminium make it more resistant to heat.
Sulfuric acid resistance is extremely high in Alloy 20. This alloy has also been demonstrated to have suitable resistance to phosphoric acid, nitric acid, and aqueous salt solutions. As a result of its resistance to pitting and crevice corrosion, Alloy 20 is a great choice when chloride stress corrosion cracking is a concern. When exposed to chloride ion environments, extreme caution should be exercised because the rate of corrosion can increase dramatically. It is used in a wide range of industries, such as chemical processing, petrochemical and refining, marine and pharmaceutical processing, as well as food processing. Storage tanks, mixing tanks, agitators, pump and valve parts, food processing equipment, fasteners, and fittings are some of the end-use applications for this material. According to the ASME, applications are limited to a maximum temperature of 1000°F. Also critical is determining whether or not the required corrosion resistance can be achieved in the given environment.
