Duplex Steel UNS S31803 Flanges are made from a duplex stainless steel alloy. This alloy offers superior corrosion resistance and is especially resistant to stress corrosion cracking. It also provides higher strength than other austenitic stainless steel, making it ideal for high-pressure applications. These flanges are available in blind, slip-on, and weld neck designs to suit various applications and have good weldability properties. ASME 16.5 Duplex Steel UNS S31803 Flanges can be used in temperatures ranging from -50°F up to 1200°F.

Duplex Steel UNS S31803 Flanges is a common steel alloy used to manufacture flanges. It comprises 25% chromium, 4.5% nickel, 7% manganese, and 0.3% molybdenum. This combination offers superior strength and corrosion resistance compared to other grades of stainless steel. Two types of Duplex Steel UNS S31803 Flanges are available– Slip On Flange (SOF) and Socket Welding Flange (SWF). Slip On Flanges are best suited for low-pressure applications like water pipe systems. At the same time, Socket Welding Flanges are ideal for higher-pressure applications such as hydraulic systems or oil pipelines. Different types of products are available, such as Alloy Steel ASTM A182 F11 Round Bars, Incoloy 925 Flanges, etc.

2205 Duplex Flanges have a wide range of uses and benefits. 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. Duplex Steel S32205 Flanges, Duplex Steel Pipe Fittings, and many more grades are also available.
