Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Duplex Steel S31803 Flanges, which are used to nickel to maintain an austenitic composition at lower temperatures. Duplex Steel S31803 Slip On Flanges is austenitic stainless steels with superior corrosion resistance to stainless steel 317. These Duplex Steel S31803 Threaded Flanges is suitable for welding because it has carbon content lower than 301 to 303 series alloys to avoid carbide precipitation in welding applications. Equipment in the chemical, food, paper, mining, and pharmaceutical and petroleum industries often includes Duplex Steel S31803 Weld Neck Flanges.

The addition of molybdenum and slightly higher nickel content make Duplex Steel S31803 Blind Flanges suitable for architectural applications in severe settings, from polluted marine environments to areas with sub-zero temperatures. Duplex Steel UNS SS3180300 Socket Weld Flanges also offer higher creep, stress – to – rupture and tensile strength at elevated temperatures, excellent corrosion resistance and strength properties, and they are well suited for fabricated or formed applications.
Duplex Steel S31803 Lap Joint Flanges is ideally suited for applications requiring corrosion resistance superior to Type 316 and has good elevated temperature strength. Duplex Steel S31803 Ring Joint Type Flanges is the lower carbon version and is immune from sensitization. Therefore, Duplex Steel S31803 Spectacle Blind Flanges is very frequently used in heavy gauge welded components. Duplex Steel S31803 Nippolet Flanges is considered resistant to pitting corrosion in potable water with chlorides at ambient temperatures, reducing at 60 Degree C.
