Hastelloy C-276 Welding Wire

Hastelloy C-276 Welding Wire is formulated for joining and overlay work in equipment exposed to severe chemical corrosion. Its nickel-molybdenum-chromium composition provides strong resistance to wet chlorine, sulfuric and hydrochloric acids, chlorides, and mixed oxidizing or reducing media, helping maintain weld integrity in harsh service.
The wire supports smooth deposition and reliable weld performance on Hastelloy C-276 and compatible nickel alloys, making it suitable for repairing reactors, scrubbers, piping, tanks, and other process equipment. It is widely used in chemical processing, pollution control, petrochemical, offshore, and power-generation applications where durable, corrosion-resistant welds are required.
