Hastelloy C276 Buttweld Fittings are pipe fittings made from Hastelloy C276, a versatile nickel-molybdenum-chromium alloy that exhibits exceptional corrosion resistance in highly corrosive environments. The key components of this alloy include approximately 55% nickel, 16-17% molybdenum, 15-17% chromium, and small amounts of iron, tungsten, and cobalt. This unique composition gives Hastelloy C276 its outstanding resistance to a wide range of aggressive media, including strong acids, chlorides, and reducing agents. As a result, it is commonly used in chemical processing, petrochemical, and waste treatment industries, where it provides reliable performance and extended service life in harsh conditions.
Hastelloy C276 Buttweld Fittings offer several advantages, including high mechanical strength, excellent fabricability, and ease of welding. The alloy's ability to withstand both oxidizing and reducing environments makes it well-suited for applications in hot sulfuric acid, acetic acid, hydrochloric acid, and seawater environments. Its resistance to pitting, crevice corrosion, and stress corrosion cracking further enhances its suitability for critical applications where safety and integrity are paramount.
These fittings are available in various types, including elbows, tees, reducers, and caps, conforming to industry standards such as ASTM B366 and ASME B16.9. Proper material selection and strict quality control during manufacturing are essential to ensure the fittings' integrity and performance in demanding environments.
