Alloy C-4 Seamless Pipe for High-Temperature Corrosive Environments with Nickel Chromium Molybdenum in Seamless Cold-Drawn Tube

High-performance seamless tubes designed for high-temperature corrosive environments in chemical processing and industrial applications.

Alloy C-4 (UNS N06455) is a high-performance nickel-chromium-molybdenum alloy known for its exceptional metallurgical stability and corrosion resistance. It is the most microstructurally stable member of the widely used Ni-Cr-Mo alloy family, which is renowned for resistance to a wide range of aggressive chemicals, particularly hydrochloric acid, sulfuric acid, and chlorides.

This alloy features a face-centered cubic (FCC) lattice structure with an optimized chemical composition that ensures metallurgical stability and resistance to sensitization. With lower carbon, silicon, and iron content compared to earlier similar alloys such as Hastelloy C-276, Alloy C-4 delivers excellent stability at 650°C to 1040°C and significantly improved resistance to intergranular corrosion.

• Excellent Corrosion Resistance: Outstanding resistance to aggressive acidic media including strong acids, salts, oxides, chlorides, and sulfides.
• Excellent High-Temperature Stability: Maintains high ductility and mechanical integrity after prolonged aging at 649°C to 1038°C.
• Excellent Weldability: Easily welded using TIG, MIG, or SMAW techniques without fear of sensitization.
• Oxidation-Reduction Mixed Corrosion Resistance: Capable of withstanding both oxidizing and non-oxidizing acids.
• Good Formability: Ductile and can be cold-formed and hot-formed using standard techniques.
