Incoloy 20 2.4660 Corrosion resistance: Good corrosion resistance in concentrated sulfuric acid below 50 degrees, more than 50 degrees above. Shanghai Jiayu is not recommended. It is not an ideal material in wet process phosphoric acid and HCl, resistant to intergranular corrosion and points. Poor eclipse.
Incoloy 20 2.4660 physical properties: density 8.1g / cm3, melting point: 1350 ~ 1370 ° C, specific heat capacity: 500J / kg. K, thermal conductivity: 13.5. W (m. K), elastic modulus: 200 MPa.
Incoloy 20 2.4660 Machining and welding: The thermoforming temperature of the alloy is 970~1065 degrees. It is not suitable for the forming operation under the sensitive temperature of 650 °C. The cold forming of this alloy is similar to chrome-nickel stainless steel. The heat treatment is preferably stabilized at 940 degrees, and the intermediate annealing temperature is at a solid solution softening annealing treatment higher than 1050 degrees, and can be welded by a usual welding method.
Alloy 22 is nickel based and typically contains 22% chromium, 14% molybdenum and 3% tungsten. Iron is usually limited to less than 3%. The high chromium content of the alloy gives it a good wet corrosion resistance to oxidizing media such as nitric acid, iron and copper salts. The content of molybdenum and tungsten makes the alloy resistant to moisture reducing media such as sulfuric acid and hydrochloric acid. Alloy 22 exhibits excellent seawater corrosion resistance under stagnant and flow conditions.
At high temperatures, the high chromium content of Inconel 22 contributes to its resistance to oxidation, carburization and vulcanization. Because of its nickel-based nature, Alloy 22 resists the high temperature attack of halides such as chlorides and fluorides. With these properties, the alloy is widely used to protect steel pipes and other components in coal-fired and waste-fired boilers.
Application areas:
It is widely used in the chemical processing industry, hot sea water and hydrometallurgy. Mainly used for heat exchangers, pipes, valves, pumps, etc. in the treatment of hot H2SO4, chloride-containing solutions, Na2SO3 and other environments.
