Duplex Steel 2205 Flanges

Kalpataru Piping Solutions is a leading Duplex 2205 Flanges supplier, offering high-quality Duplex 2205 flanges known for their unique composition and exceptional performance. Our Duplex steel 2205 flanges are made from a balanced mix of ferrite and austenite, creating a dual-phase structure that provides outstanding corrosion resistance and high strength. Duplex Steel 2205 Flanges chemical composition, which includes high levels of chromium, molybdenum, and nitrogen, enables duplex flanges to form a protective layer that effectively resists various types of corrosion, including pitting and stress corrosion cracking.

Duplex 2205 Flanges material is almost twice as strong as standard austenitic or ferritic stainless steels, making our flanges ideal for high-pressure and high-temperature environments. Their excellent weldability ensures that they maintain their strength and corrosion resistance even after welding, making them a preferred choice for demanding applications. At Kalpataru Piping Solutions.

Explore our wide range of  Duplex Steel Products, including pipes, tubes, flanges, and fittings, all renowned for their exceptional corrosion resistance and durability in demanding environments.

Duplex 2205 flanges stand out for their exceptional properties. Duplex 2205 Flanges have high thermal conductivity, which is greater than that of austenitic steels, allowing them to effectively disperse heat and perform well in high-temperature operations. Additionally, their low coefficient of thermal expansion ensures stability and reliability under varying thermal conditions.

Another notable feature is duplex 2205 flanges have impressive impact toughness, making them highly effective at absorbing and dispersing energy from impacts. This minimizes the risk of cracking or fracturing, making them reliable under dynamic loads or in environments prone to shock loading. With UNS S32205 equivalents also available,

FAQ

What is a duplex flange?

Duplex stainless steel flanges are durable and ideal for applications needing high strength and corrosion resistance. They offer excellent protection against stress corrosion, pitting, and crevice corrosion, especially in chloride-rich environments.

What grade are duplex flanges?

Duplex flanges are made from austenitic-ferritic stainless steel with higher resistance to stress corrosion cracking compared to standard 304 and 316 stainless steels. Common grades include 2205, F51, F53, and F60.
