ASME SA240 UNS S31803 DIN1.4462 S32205 plate sheet coil strip

ASME SA240 UNS S31803 and S32205 Plate is a popular type of Duplex Stainless Steel that is highly sought after in various industries due to its exceptional properties. UNS S31803 and S32205 can called 2205 duplex steel, they are ASTM A240 duplex stainless steel grade. They are a type of stainless steel that contain a mix of both austenitic and ferritic phases, giving them superior strength and resistance to stress corrosion cracking.

The specification of ASME SA240 duplex steel UNS S31803 and S32205 Plate

The chemical composition of ASME SA240 UNS S31803/S32205 Plate is crucial for determining its physical and mechanical properties. It usually contains about 22-23% chromium, 3-3.5% molybdenum, and 4.5-6.5% nickel. It also contains other elements, such as nitrogen and carbon, to enhance its properties further.

ASME SA240 UNS S31803 and S32205 duplex Plate Mechanical properties

The process of manufacturing ASME SA240 UNS S31803 and S32205 duplex Plate involves several steps. First, the raw materials are carefully selected and tested for their chemical composition. Next, the materials are melted in a furnace, and the molten metal is cast into a mold to form a solid slab. The slab is then rolled into a plate of the desired thickness and cut to the required size. Finally, the plate is inspected for quality and tested to ensure it meets the necessary standards.

ASME SA240 Duplex steel Plate has excellent corrosion resistance, high strength, and good ductility. It also has good thermal conductivity and high melting point. It can withstand high temperatures and is resistant to fatigue and stress corrosion cracking.

ASTM A240 Duplex Stainless steel Plate is used in a wide range of applications, including chemical processing, oil and gas production, and power generation. It is also used in the manufacturing of heat exchangers, pressure vessels, and piping systems. Due to its outstanding performance in highly corrosive environments, it is a preferred choice for marine and offshore applications.
