Duplex Steel S31803 & S32205 Flanges Duplex stainless steel grades S31803 and S32205 are part of the duplex family and are commonly used in the production of flanges due to their excellent mechanical properties and corrosion resistance. These grades belong to the ASTM A182 standard for forged or rolled alloy and stainless steel pipe flanges, fittings, valves, and parts for high-temperature service.
Duplex stainless steel grades S31803 and S32205 are popular choices for manufacturing flanges due to their exceptional corrosion resistance and mechanical properties. These flanges serve critical roles in joining piping systems in various industries, offering reliability and longevity in demanding environments.
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. S31803 flanges are commonly used in industries such as oil and gas, chemical processing, and offshore installations, where resistance to corrosion & mechanical strength are critical.
Duplex Steel S32205 Flange is specifically used for applications with higher corrosion resistance than S31803. S32205 is a duplex stainless steel grade with improved pitting and crevice corrosion resistance. These flanges are commonly used in environments containing chloride ions, such as seawater applications, desalination plants, and chemical processing plants.
The advantages of Duplex Steel 2205 Flanges include superior corrosion resistance, especially in harsh environments with high chloride content. They offer high strength and excellent toughness, allowing them to withstand extreme temperatures and pressures. Duplex Steel 2205 Flanges also provide good weldability & formability, making them easy to work with during installation. Their combination of properties makes them ideal for demanding applications, ensuring reliable & long lasting performance.
