Duplex Steel S31803 Flanges are flange fittings made from duplex stainless steel grade S31803. Duplex stainless steel offers excellent corrosion resistance and high strength, making it suitable for various industrial applications. They are most commonly used in seawater applications because they can withstand saline conditions without corroding or rusting. They also have excellent strength due to their high alloy content, which makes them resistant to fatigue and wear and tear in high-pressure environments like oil pipelines or hydraulic systems. Due to their superior corrosion resistance properties, they require less maintenance than other materials like carbon steel or iron.

DIN 1.4462 Flange offer several advantages over other materials, including superior strength, durability, and corrosion resistance, making them ideal for seawater applications and high-pressure environments like oil pipelines or hydraulic systems. UNS S31803 Flange is an excellent option for applications that require superior corrosion resistance and higher strength. They are available in various designs to suit multiple needs and can be used in different temperatures. The sizes range from ½ inches to 48 inches. The pressure ratings range from 150LBs to 2500LBs and others. There are also different types of flanges used in different applications. The ASME SA182 F51 RTJ Flange has two rings as two halves and they are connected at the joint by welding. The flanges also have different faces as raised face, flat face and the ring type joint.

As a duplex stainless steel, UNS S31803 combines the most effective traits of austenitic and ferritic stainless steels, leading to an impressive fusion of strength and corrosion resistance. The UNS S31803 Flanges display high yield strength, almost double that of conventional austenitic stainless steel grades. This strength is a significant advantage as it allows these flanges to maintain their integrity even under substantial stress. This increased durability can minimise maintenance, providing reliability often vital for high-stakes settings. Notably, the UNS S31803 Flanges also showcase admirable resistance against various forms of corrosion, including pitting and crevice corrosion. This resistance is particularly valuable in applications exposed to chloride-containing environments. Such resistance is attributed to duplex stainless steel's high chromium, molybdenum, and nitrogen content.The Duplex Stainless Steel Weld Neck Flange has a welded neck on it for extra grip prior to and after welding.
