Kalpataru Piping Solutions is a top exporter and supplier of duplex stainless steel products, including UNS S31803 Round Bars, preparing from premium-quality raw materials and meeting both national and international standards. These round bars are nearly twice as strong as standard stainless steels, allowing for reduced wall thickness and material cost savings. When used in heat exchangers, Duplex Steel S31803 Round Bars offer even greater advantages. We also supply Duplex Steel Hexagon Bars to Africa, Duplex DIN 1.4462 Welding Rods to Egypt, and manufacture Duplex Steel Bars and Rods locally in India.
The WNR 1.4462 Bars have lower nickel content, which improves their thermal conductivity compared to austenitic stainless steels. We provide these duplex steel products in customized shapes and sizes to match specific client needs, all at competitive prices. Duplex Steel UNS S31803 Bars are widely appreciated for their strength, easy weldability, and excellent workability. They also resist sulphide stress corrosion effectively. While duplex stainless steels are resistant to stress corrosion cracking, they are less prone to it compared to ferritic stainless steels. These products are ideal for use in marine environments, effluent scrubbing systems, and other high-chloride settings. To avoid brittleness caused by exposure to 475°C, rapid cooling during heat treatment is essential.
What is UNS S31803 Material?
UNS S31803 is a duplex stainless steel alloy, also known as ferritic-austenitic stainless steel. It features a balanced chemical composition that provides outstanding mechanical strength and corrosion resistance in demanding environments. This alloy combines the benefits of both austenitic and ferritic stainless steels, offering high stress tolerance and low corrosion rates. UNS S31803 is commonly used in structural components and pressure vessels, making it suitable for applications with heavy loads or high temperatures. Additionally, its ability to achieve a polished and attractive finish makes it versatile and durable for a wide range of industrial uses.

FAQs
What is duplex S31803?
UNS S31803/2205 is a duplex stainless steel grade with a ferritic-austenitic microstructure, typically consisting of 40-50% ferrite when annealed. It combines the high strength of ferritic grades with the corrosion resistance of austenitic grades.
What is the difference between uns S31803 and SS316?
Compared with SS316, UNS S31803 has about twice the yield strength. The Pitting Resistance Equivalent Number (PREN) of UNS S31803 is around 34, while for SS316 it is 25, indicating that UNS S31803 has significantly better resistance to pitting corrosion.
What is a material equivalent to uns S31803?
UNS S31803 is a duplex stainless steel with 22% chromium. Equivalent materials include DIN 1.4462, a European standard for duplex steel, and ASTM A182 F51, a specification for forged stainless steel flanges and fittings.
