2205 Stainless Steel Welded Pipe

Grade: 2205/UNS S32205/UNS S31803/W.Nr.1.4462

Size: 12mm*0.5mm-2000mm*100mm

Length: 1000mm-12000mm

Standard: ASTM A312, ASTM A269, ASTM A790, ASTM A789 etc.

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.
