There is no doubt that Ratnaexports.com is the leading manufacturer, supplier, and exporter of Duplex Steel Round Bars/Rods. As a supplier of duplex steel, we supply it in grades such as UNS S31803 and S32205. We manufacture bars and rods with the highest quality raw materials and technology, following national and international standards. Several sizes, specifications, thicknesses, finishes, and colors of duplex steel round bars are available. Moreover, we offer them in custom specifications to meet the needs of many industries. The stainless steel austenitic-ferrite round bar, UNS S31803, is also referred to as a stainless steel austenitic-ferrite round bar due to the equal amounts of austenite and ferrite in the bar. They have characterized by both austenite and ferrite microstructures, which provide high tensile strength and excellent resistance to stress corrosion cracks. Undoubtedly, these Duplex Steel Bars offer outstanding corrosion resistance, a high level of toughness, and a high level of tolerance.
UNS S32205 Rods are characterized by their high chloride stress corrosion cracking resistance, chloride breaking resistance, ease of handling, high strength, weldability, formability, and silent properties. The chromium, nitrogen, and molybdenum content are among the most significant factors influencing the chloride crevice and pitting corrosion resistance of Duplex Steel UNS S31803 Rods.
There are some limitations to using Duplex Steel 2205 Round Bars, such as the fact that it suffers from precipitation of brittle microconstituents at temperatures over 300 degrees Celsius, as well as the transition that occurs at temperatures below 50 degrees Celsius. Duplex steel round bars should be hot worked between 954 and 1149 degrees Celsius (1750 and 2100 degrees F).
Rods made from Duplex steel have excellent pitting and uniform corrosion resistance, high strength, and high resistance to stress corrosion cracking (SCC). Our company supplies round bars and rods to numerous industries such as seawater desalination plants, oil and gas equipment, paper & pulp manufacturing, offshore technology, chemical and food processing, fertilizers, sugar mills & distilleries, cement factories, shipbuilding companies, and petroleum processing plants.
Our company must offer a variety of test certificates along with our Duplex Steel Round Bars and Rods. These documents include Mill Test Certificates, EN 10204 3.1/3.2, Chemical Reports, Mechanical Reports, PMI Test Reports, Visual Inspection Reports, Third Party Inspection Reports, etc.
This particular alloy has several benefits. While the alloy possesses good elasticity, it is hard, preventing Duplex Steel UNS S31803 Bars from getting deformed, especially at high temperatures, where any conventional steel alloy would change shape. In particular, this characteristic is crucial for applications that require specific form retention as a prerequisite. Considering that power plants and even chemical plants have a lot of exothermic reactions occurring throughout the process, alloys like the ASTM A276 F51 Duplex Round Bar, capable of withstanding high heat and remaining in their shape, are required.
Due to the nickel content within these alloys, the UNS s31803 f51 rods could withstand elevated temperatures due to their chemical composition. However, using the A276 s31803 material above 600° F is not recommended since the material could lose its properties as drastically as this temperature at that point. When placed at elevated temperatures, US S31803 round bar performs much better than some types of austenitic steel.
