2205 Stainless Steel Pipe is a widely used duplex grade combining high mechanical strength with excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Its balanced austenitic-ferritic microstructure provides a strong performance-to-weight ratio. 2205 pipe is commonly selected for oil and gas, chemical processing, marine, desalination, pressure equipment, and industrial piping exposed to chloride-containing environments.
