Duplex steel is a type of stainless steel known for its high strength and corrosion resistance. Duplex steel is comprised of a mixture of austenitic and ferritic steel grades, giving it a unique chemical composition. The Duplex Steel S31803/1.4462 Sheet/Coil/Plates are some of the most popular forms of duplex steel used for various applications.
Duplex Steel S31803 Sheet Features: The Duplex Steel S31803 Sheet is a versatile duplex steel used in several applications. It is known for its high strength and durability, ideal for harsh environments. The S31803 sheet has excellent corrosion resistance properties, making it a great choice for applications exposed to chlorine, acids, and other corrosive substances. The S31803 sheet is also resistant to pitting and crevice corrosion, which can cause severe damage to other grades of stainless steel.

Duplex Steel S31803 Coil Corrosion Resistance The Duplex Steel S31803 Coil is a corrosion-resistant duplex steel form that is used in a wide range of applications. One of the most significant advantages of using the S31803 coil is its ability to withstand harsh environments without corrosion. It has excellent resistance to stress corrosion cracking, a common issue with other materials. In addition to its corrosion-resistant properties, the S31803 coil has excellent toughness and strength, making it ideal for applications where high strength and durability are crucial.
Duplex Steel 1.4462 Plates Chemical Composition: The Duplex Steel 1.4462 Plates are known for their unique chemical composition. It is a blend of austenitic and ferritic steel grades that provides superior strength, durability, and corrosion resistance. The chemical composition of 1.4462 plates typically consists of 22% chromium, 5% nickel, 3% molybdenum, and less nitrogen. The combination of these elements makes the 1.4462 plates highly resistant to corrosion, especially in environments involving chloride and hydrogen sulfide.
Duplex Steel S31803 Sheet Applications The Duplex Steel S31803 Sheet is widely used in various applications across different industries. It is commonly used in construction, specifically for structures requiring high strength and excellent corrosion resistance. The S31803 sheet is also commonly used in the chemical and petrochemical industries, where it is exposed to harsh environments and corrosive substances. Other applications of the S31803 sheet include pressure vessels, oil and gas production, and heat exchangers.
Duplex Steel S31803 Coil Heat Treatment The Duplex Steel S31803 Coil is typically heat-treated to achieve the desired mechanical properties. The heat treatment involves heating the coil to a specific temperature for a set time, followed by quenching or cooling it rapidly. The heat treatment is vital as it increases the coil's strength, hardness, and toughness. The heat treatment process of the S31803 coils also reduces the risk of stress corrosion cracking.
