Corrosion is a major concern for industries dealing with aggressive chemicals, acids, and saltwater environments. The cost of corrosion can be staggering, with an estimated $2.5 trillion lost globally every year to corrosion-related damage. This is where corrosion-resistant alloys, such as Hastelloy C22, come in. Hastelloy C22 is a high-performance nickel-chromium-molybdenum-tungsten alloy with superior corrosion resistance properties. In this blog, we will explore the exceptional corrosion resistance of Hastelloy C22 bars, especially in aggressive chemical environments.
What are Hastelloy C22 Bars?
Hastelloy C22 bars are made from the Hastelloy C22 alloy, one of the most versatile corrosion-resistant alloys available. The alloy's chemical composition provides excellent resistance to reducing and oxidizing environments, making it suitable for aggressive chemical environments. Hastelloy C22 bars are available in various shapes and sizes, including round, square, hex, and flat bars.
Corrosion Resistance Properties of Hastelloy C22 Bars
The corrosion resistance properties of Hastelloy C22 bars are its biggest selling point. The alloy resists corrosive environments, including wet chlorine, hydrogen chloride gas, sulfuric acid, and nitric acid. Hastelloy C22 bars also provide excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. This makes them a preferred choice for industries dealing with harsh chemicals, such as chemical processing, pharmaceuticals, and petrochemicals.
One of the significant advantages of Hastelloy C22 bars is their ability to resist localized corrosion in chloride-containing environments. Hastelloy C22 bars have a high chromium content, forming a passive layer on the material's surface, protecting it from corrosion. The alloy's molybdenum content also helps prevent localized corrosion by improving the material's resistance to pitting and crevice corrosion.
Hastelloy C22 bars are also resistant to attack by reducing acids, such as hydrochloric and sulfuric, known for their aggressive nature. The alloy's tungsten content helps improve the material's oxidation resistance, making it suitable for use in high-temperature applications. Hastelloy C22 bars do not undergo stress-corrosion cracking when exposed to a high-stress environment with corrosive media.
Benefits of Using Hastelloy C22 Bars
Improved Safety: Hastelloy C22 bars can operate in hazardous and corrosive environments, providing improved safety for workers and equipment.
Longevity: Hastelloy C22 bars are durable and corrosion-resistant, offering extended service life and reducing the need for frequent replacements.
