S31803 duplex stainless steel material is used in applications where high corrosion rates are expected. Due to the addition of molybdenum to UNS S31803 materials, they have very low wear in chloride-ion-rich solutions. Due to the addition of chromium, steel-grade S31803 piping is also resistant to localized and pitting corrosion. Alloy UNS S31803 material is lightweight because of the low nickel content in it. The UNS S31803 product also maintains high tensile strength through its ferritic microstructure. This allows the S31803 duplex steel pipe material to withstand high tension and pressure in hydraulic systems without corroding at medium temperatures. Therefore, Stainless Steel S31803 pipe material is used in applications where weight reduction is necessary without compromising strength.
S31803 duplex steel is a class of steel in which the microstructure of the steel contains ferritic and austenitic metal phases in its metallurgical properties. This gives UNS S31803 duplex stainless steel pipe the best qualities on both sides of the spectrum. This also leads to undesirable properties such as intergranular precipitation at high temperatures (typically above 300°C). Note, therefore, that it is generally not suitable for use above 250°C, nor below -50°C, due to the formation of brittle deposits. This is because the transition from ductile to brittle results in lower impact toughness.
