Quantity:

Hastelloy C22 is a high-end alloy that is commonly used for its high-temperature strength and excellent resistance to harsh chemicals. It is a nickel-chromium-molybdenum-tungsten alloy with the addition of other elements like cobalt, iron, and copper. Hastelloy C22 is generally manufactured using a forging process that involves heating the metal to a high temperature and then compressing it into a desired shape.

Chemical Composition of hastelloy C22 alloy

The chemical composition of Hastelloy C22 plays a significant role in its overall properties. It contains about 22% chromium, 12.5% molybdenum, 3% tungsten, and 2.5% iron. The alloy also has small amounts of cobalt and copper to enhance its corrosion resistance. The combination of these elements makes Hastelloy C22 highly resistant to stress corrosion cracking, pitting, and crevice corrosion.

Mechanical Properties

Hastelloy C22 is a high-strength alloy that exhibits superior mechanical properties at high temperatures. It has a tensile strength of 1144 MPa and a yield strength of 482 MPa at room temperature. The alloy gains an increasing strength as the temperature rises, allowing it to maintain its structural integrity at extreme temperatures. Hastelloy C22 also has good ductility and can withstand high levels of strain without showing signs of failure.

Applications of Hastelloy C22 Superalloy Forgings

Hastelloy C22 is widely used in various industries, including chemical processing, aerospace, and oil and gas. Its resistance to high temperatures and harsh chemicals makes it ideal for use in applications involving strong acids, alkalis, and oxidizing agents. It is also commonly used in manufacturing heat exchangers and reactors designed to operate at high temperatures and pressures.

In conclusion, Hastelloy C22 is a high-performance alloy that exhibits excellent mechanical properties and high resistance to harsh chemicals. Its chemical composition allows it to maintain its structural integrity even at elevated temperatures, making it ideal for use in applications involving high-temperature and high-pressure environments. With its superior properties, this alloy has become a popular choice in various industries and is set to continue being one of the preferred materials for high-stress applications.
