A Duplex Steel Round Bar
A Duplex Steel Round Bar is a type of steel bar known for its unique combination of properties derived from the duplex stainless steel material it’s made from. Duplex stainless steel contains a dual-phase microstructure consisting of approximately equal parts of austenite and ferrite phases, which impart exceptional strength, corrosion resistance, and toughness.
Products like the Duplex 2205 Round Bar, Duplex UNS S32205 Round Bars, and Duplex UNS S31803 F51 Round Bars are among the most demanded in high-performance applications because they offer outstanding strength and corrosion resistance. As a top Duplex Steel Bars Supplier, we ensure our bars meet the rigorous requirements of clients from critical industries like marine, energy, and petrochemical sectors.
Manufacturing Process Of Duplex Steel Bars
Melting
The first step in the process is melting raw materials in an electric furnace. These raw materials are typically iron ore, chromium, nickel, and other elements in exact amounts. Our Duplex UNS S32205 F60 Round Bars and Duplex UNS S32205 Bars undergo a precise melting process to ensure metallurgical accuracy.
Casting
After melting, the metal is put into molds to form slabs or billets. The processing of these first forms is then continued.
Hot Rolling
After being heated, the billets are shaped into long, thin rods by going through a series of rolling mills. Because the metal is heated above its recrystallization temperature during this operation, it is known as hot rolling.
Annealing
After that, the rods are annealed to reduce stress and enhance machinability. To do this, the rods must first be heated to a certain temperature and then gradually cooled.
Cutting
Lastly, shearing machines or other cutting techniques are used to cut the rods to the required length.
We follow strict quality control at each stage to produce products like Duplex UNS S31803 Bars, Duplex 2205 Round Bar, and Duplex UNS S32205 F60 Round Bars with unmatched performance characteristics.
Duplex steel bars are available in a wide range of sizes to suit different applications and requirements. The Duplex steel bar sizes can vary depending on the diameter and length of the bars. Duplex steel bars can have diameters ranging from as small as 6mm (0.236 inches) up to larger diameters exceeding 300mm (11.8 inches) or more. Duplex steel bars typically come in standard lengths, often ranging from 3 meters (10 feet) to 6 meters (20 feet). However, custom lengths can also be available based on specific project needs.
As a seasoned Duplex Steel Round Bars Importer, Pearl Steel ensures our product range includes Duplex UNS S32205 Round Bars, Duplex UNS S31803 Bars, and custom-finished sizes for niche applications.
Duplex Steel Round Bar Equivalent Grade
Duplex Steel Round Bar Equivalent Grade is a critical aspect that ensures compatibility and interchangeability across international standards. One commonly utilized grade is Duplex 2205, which is equivalent to UNS S32205 or S31803 in the United States. This grade exhibits a balanced dual-phase microstructure, comprising austenitic and ferritic phases, providing an optimal combination of strength and corrosion resistance. Internationally, it aligns with European standards as 1.4462 according to EN 10088-3.
As a professional Duplex Steel Bars Supplier, Pearl Steel ensures that each Duplex UNS S32205 Bars and Duplex UNS S31803 F51 Round Bars product conforms to these grades to ensure quality and performance worldwide.
Chemical Composition of Duplex Steel Round Bar
The chemical composition of Duplex Steel Round Bars typically comprises a carefully balanced blend of elements, crucial for achieving its distinctive properties. Primarily composed of iron, duplex stainless steel incorporates significant amounts of chromium, typically ranging from 21% to 23%, which enhances its corrosion resistance, especially in harsh environments. Additionally, it contains approximately 4.5% to 6.5% nickel, contributing to its high strength and ductility. Molybdenum, present in quantities of around 2.5% to 3.5%, further improves corrosion resistance, particularly against chloride-induced pitting and crevice corrosion. Nitrogen, typically between 0.08% and 0.20%, aids in stabilizing the austenitic phase and enhancing mechanical properties. Other elements such as manganese, silicon, and carbon are also carefully controlled to optimize the microstructure and mechanical performance of duplex steel.
This precision is what makes our Duplex 2205 Round Bar, Duplex UNS S32205 F60 Round Bars, and Duplex UNS S31803 Bars reliable for mission-critical operations.
