Duplex Steel S31803 Pipes

s31803 Duplex steel pipes are composed of chromium, nickel, and molybdenum in a specific blend. This combination gives these pipes superior strength and excellent corrosion resistance properties. Another critical component in the composition of this type of pipe is nitrogen, which helps to further bolster its yield strength without compromising any ductility or toughness that's inherent within the steel material itself. Furthermore, this alloy also has meager thermal expansion rates along with high thermal conductivity ratings, indicating it can be used for exact applications such as in heat exchangers to be able to tolerate significant fluctuations in both pressure and temperature over long periods.

Duplex steel s31803 pipe is a popular choice of material for applications requiring superior strength, corrosion resistance, and toughness. This duplex steel contains specific ratios of molybdenum, chromium, and nickel, making it an optimal material for many industries. In addition to its hardwearing properties, this particular grade of stainless steel is exceptionally resistant to chloride stress corrosion cracking and highly resistant to general corrosion from most organic acids, salts, and halide environments. This makes it an excellent option for water handling and transport systems such as oil pipeline systems or seawater cooling pipes. Its anti-corrosive solid properties make it a popular choice for chemical processing systems or heat exchangers. Finally, its tensile strength makes it ideal for structural applications and general fabrication projects requiring high strength with easy fabrication capabilities.

Duplex Steel S31803 Pipes FAQ's  

It Varies, But Generally It Is Around INR 150/Kg To INR 300/Kg

Duplex steel S31803 pipes are not magnetic due to their duplex microstructure which contains both ferritic and austenitic phases. This makes them suitable for use in non-magnetic applications.

Yes, Duplex steel S31803 pipes are known for their corrosion resistance properties due to their high chromium and molybdenum content. They also have a duplex microstructure which improves resistance to stress corrosion cracking and pitting. They are suitable for use in harsh environments.
