Duplex 2304 Pipes / Tube

Duplex Steel 2304 Pipe, Duplex Steel 2304 Hexagonal Pipes Tube In Malaysia, UNS S32304 Hollow Pipes Tube In Nigeria, Alloy 2304 Hexagonal Pipes Tube In SOUTH AFRICA, ASTM A790 Duplex Steel S32304 Bush Hex Pipes Tube.

UNS S32304 Duplex Steel Electropolish ERW Pipes Tube, Duplex Steel WNR 1. 4362 Rectangular Pipe, UNS S32304 Duplex Steel Welded Pipes Tube In Australia, UNS S32304 Duplex Steel Seamless Bush Hex Pipes Tube In Germany.

We manufactured, export & supply Lean Duplex 2304 pipes in accordance with international ASTM standards Duplex 2304 Pipes / TubeWelded pipe ASTM A790 UNS S32304 Our UNS S32304 Duplex Steel Pipes are stronger and harder as compared to normal steel. However, these UNS S32304 Duplex Steel Pipes are not as challenging to corrosion as stainless steel.

Duplex 2304 is austenitic-ferritic stainless steel used for corrosive environments and is capable to resist localized corrosion such as pitting, crevice corrosion, and stress corrosion cracking. The austenitic-ferritic chemical composition results in mechanical properties that are able to cope with high-stress conditions where to use of ordinary austenitic stainless steel will result in mechanical failure.

We manufacture, export & supply UNS S32304 Duplex Steel Pipe to spheres of the industries ranging from basic industries such as Sugar, Paper, Textile, Engineering to more complex such as Oil & Gas, Petrochemical, Chemical & Fertilizers, Power Generation and Nuclear Industries.

Beneficial key Properties:-

  • Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environments

  • Chromium, molybdenum, and nitrogen content also provide high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions

  • Resistant to chloride stress corrosion cracking and temperatures of up to about 302°F (150°C)

  • The presence of ferrite provides for good performance of Duplex 2205 in caustic environments

  • Similar to other duplex stainless steels, Duplex 2205 has good oxidation resistance at high temperatures
