Alloy 20 is a high nickel alloy used for various purposes. It has a high nickel content of approximately 33%. These high nickel composition nuts were specifically designed to work with high chloride conditions. The nickel contents do not let the chlorine in applications cause any corrosion. It also contains high molybdenum and copper which is a very important element to avoid general corrosion Alloy 20 has columbium to stabilize the alloy. Hence, alloy 20 nuts are reputed for their easily weldable feature using the most basic procedures. The columbium prevents carbide precipitation and lowers the risk of intergranular corrosion. It also has a special ability to prevent appliances from corroding due to the presence of severe acids such as phosphoric acid, dilute acetic acid, and sulfuric acid, which are the most significant. Even after consisting of high proportions of nickel, alloy 20 nuts are available at very reasonable prices in the market. They perform similar to the costly metals of Inconel and Hastelloy. Carpenter’s alloy as it is popularly known has multi-various functions and is used in several different industries. Another reason for its wide range of applications is its heat resistance. It can be easily used in applications and procedures which work in moderately high-temperatures. Even after being in contact with the harsh temperature Alloy 20 nuts are capable to sustain their mechanical properties Alloy 20 is fabricable and not so easy to be contaminated. Carpenter’s alloy nuts are used in various industries like flue-gas desulfurization, metal cleaning and pickling equipment, pharmaceuticals, and the most important applications involved in marine engineering and sea-water-related industries.
