Hastelloy C276 is a highly sought-after superalloy that is composed of a combination of nickel, molybdenum, chromium, and tungsten. This alloy is widely used in various industries due to its exceptional properties. In particular, the presence of molybdenum and nickel in Hastelloy C276 makes it highly resistant to corrosion even under extremely harsh conditions. Additionally, the inclusion of chromium in the alloy helps to form a protective surface layer that prevents oxidization.
One of the most significant advantages of Hastelloy C276 is its suitability for welding applications. This is due to its low carbon content, which reduces the likelihood of carbide precipitation. As a result, optimal corrosion resistance can be achieved without the need for additional treatment after welding.
Overall, Hastelloy C276 is a high-performance alloy that offers exceptional corrosion resistance and durability. Its unique composition and properties make it an ideal choice for use in a wide range of industrial applications.
| Hastelloy Alloy | Ni | Cr | Co | Mo | FE | W | Mn | C | V | P | S | Si |
| C276 | Balance | 14.5-16.5 | 2.5 Max | 15.0-17.0 | 4.0-7.0 | 3.0-4.5 | 1.0 Max | 0.01 Max | 0.35 Max | 0.04 Max | 0.03 Max | 0.08 Max |
The corrosion-resistant Hastelloy alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of geothermal, solar energy, oil and gas and pharmaceutical. The benefits of Hastelloy process equipment include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication.
Hastelloy B-3 alloy possesses outstanding resistance to non-oxidizing acids, such as hydrochloric acid and sulfuric acid. The advantages of B-3 alloy over previous B-family alloys are enhanced thermal stability and improved fabrication characteristics. The recently developed Hastelloy Hybrid-BC1, will handle stronger non-oxidizing acids than C-type alloys and will tolerate oxidizing impurities that B-type alloys will not.
On the basis of their chemical composition, the Hastelloy Steel Pipe is then classified into different grades. Mechanical properties of the ASTM B622 Hastelloy Seamless Pipes material such as tensile strength, yield strength, and elongation properties are to be measured. Tests such as Tension test, hydrostatic test, and non-destructive electric tests need to be performed on each Hastelloy Alloy Custom Pipe.
