Duplex steel S31803 is a type of stainless steel that has recently gained popularity due to its superior corrosion resistance properties. Its two-phase microstructure, combining austenitic and ferritic phases, gives it a versatile range of properties ideal for various applications. Among its different forms, the flat, patta, and flat bar forms are the most widely used ones. Duplex Steel S31803 Flat comes in various forms: hot-rolled, cold-rolled, and annealed. Hot-rolled flats have a rough and thick surface, while cold-rolled flats have a thinner, smoother surface. Annealed flats are heat-treated to remove stress, making them more malleable and easier to cut. Hot-rolled flat bars are best suited for heavy-duty applications, whereas cold-rolled flats are more commonly used in decorative applications.
Duplex Steel S31803 Patta is commonly used to fabricate brackets, frames, and supports due to its high strength and resistance to stress corrosion cracking. It is also used to construct chemical processing equipment, pipelines and heat exchangers, offshore platforms, and desalination plants. Additionally, it finds application in the food processing industry as food contact surfaces, where hygiene and resistance to corrosion are critical.
