1.4462 duplex is a material with many good properties

Type 1.4462 duplex steel, also known as UNS S31803 or 2205 duplex, is a high-performance steel alloy that combines the best properties of ferritic and austenitic stainless steel. This type of steel is well known for its excellent corrosion resistance and high strength. Duplext steel 1.4462 is often used in demanding industrial applications where both strength and corrosion resistance are important. Here are some typical uses:

• The oil and gas industry: It is used for pipelines, heat shields, and other components exposed to corrosive environments and high pressures. Its resistance to sulphide stress corrosion cracking makes it ideal for use offshore.
• Chemical industry: Duplext steel 1.4462 is resistant to a variety of chemicals, including acids and bases, making it a popular choice for reactors, heat exchangers, and tanks used in the chemical process industry.
• desalination plants: Due to its ability to resist corrosion in chloride environments, it is often used in components that are in contact with seawater, such as in desalination plants to produce drinking water.
• The paper and pulp industry: This industry uses duplex steel to make parts that need to be resistant to the corrosive chemicals used in the process of breaking down wood into pulp.
• Building and bridge structures: Its high strength-to-weight ratio makes it an attractive material choice for structural applications in aggressive environments, such as bridges and support structures in marine or coastal areas.
• Water treatment plants: Used in components that require high corrosion resistance to treated and untreated water, including pumps, valves, and pipework.
• Marine applications: Due to its excellent corrosion resistance to seawater, it is often used for the construction of marine infrastructures such as jetties, piers, and boat docks.
