Table Of Content
Duplex 2205 / UNS S31803 Bars And Wires are excellent Duplex Steel grade Bars with efficient corrosion resistance and superior strength. These bars are recommended for utilization in chloride corrosion applications and also prevent general corrosion with adequate resistance. In addition, it offers long-term use in moderate temperatures and retains the austenitic structure of Duplex 2205 steel grade. UNS S31803 Bars are made from UNS S31803 containing the higher Nitrogen content value, consequently increasing the corrosion resistance of bars.
These Duplex 2205 Bars have several specifications and incorporate Bars with different shapes and sizes. Suitable bars out of square, round, or hex shapes are availed with excellent finish and reasonable rates. These bars are Black finished or Bright Polished, with Rough Turned, Matt Finish surface. UNS S31803 bars are obtained with superior strength and are recommended in general corrosion environments. It prevents the pitting effect and remains tough under higher stress and rupture.
Duplex 2205 is nitrogen augmented Stainless Steel combining ferritic and austenitic alloy features. Thus it is highly strengthened with the excellence of corrosion cracking prevention, including superb fabricability. It contains 22% Chromium and 4-6% Nickel added in Iron with Molybdenum in adequate amounts. Nitrogen and Carbon are added to enhance corrosion resistance efficiency and strength. It is effectively used for a broad scope of utilization among Duplex series Stainless steel. It is work-hardened since it is unable to process under heat treatment.
Excellent features of Duplex 2205 Bars:
Duplex 2205 Bars excellently functions in marine surroundings and prevents cracking in chloride stress decomposition with outstanding resistance. Duplex 2205 / UNS S31803 Bars And Wires are widely used in chemical, oil, and gas industries for processing and equipment.
UNS S31803 bars reveal excellent weldability with effective functioning. Thus long service is provided with decreased reducing effect. These bars are heat resistant in high temperatures, and the annealing process is conducted to avoid embrittlement at higher temperatures.
