About Hastelloy C4 Tubing
Hastelloy C4 tubing is manufactured from nickel-molybdenum-chromium alloy, which is well-known for its excellent corrosion resistance, especially in chemical applications. Hastelloy C4 (UNS N06455) can resist both oxidation and reduction environments, and it is ideal for various applications where high temperatures and chemical attacks are anticipated. This alloy is immune to localized corrosion, stress corrosion cracking, and pitting and is thus well suited for use in harsh industrial environments.
Exceptional Corrosion ResistanceHastelloy C4 Tubing is specifically engineered for use in highly corrosive environments. Its robust material composition-nickel 65%, chromium 16%, molybdenum 16%-delivers remarkable resistance to a wide range of chemical agents, oxidizing and reducing media, and chloride-induced stress corrosion cracking. This makes it a preferred choice for industries where reliability and longevity are paramount.
Versatile Mechanical and Thermal PerformanceWith a tensile strength of 690 MPa and the ability to operate safely between -196C and 900C, Hastelloy C4 Tubing delivers outstanding mechanical strength and thermal stability. Its solution-annealed finish ensures optimal performance, and the material's non-magnetic nature in the annealed condition makes it especially suitable for sensitive applications.
Customizable for Diverse ApplicationsAvailable in outer diameters ranging from 12.7mm to 50.8mm and wall thicknesses from 1.5mm to 6mm, Hastelloy C4 Tubing can be tailored to meet specific size and length requirements. Surface finishes such as annealed, polished, and pickled, along with various end finishes, allow easy adaptation to a wide array of industrial uses, including chemical processing, power generation, and pharmaceutical manufacturing.
