Duplex 2205 Seamless Pipes are crafted from alloys that exhibit a combination of austenitic and ferritic properties. This unique composition provides these pipes with exceptional resistance to corrosion and excellent tensile strength. The 2205 Seamless Welded Pipes comprise approximately 22 percent chromium, 3 percent molybdenum, and 5 to 6 percent nickel. Developed specifically to address common corrosion issues faced by the 300 series stainless steels, Duplex 2205 Pipe is a nitrogen-enhanced duplex stainless steel.

The term "Duplex" refers to a group of stainless steels that possess neither purely austenitic characteristics, like 304 stainless steel, nor exclusively ferritic attributes, like 430 stainless steel. The structure of UNS S31803 duplex steel Pipe consists of pools of austenite surrounded by a continuous ferrite phase. In the annealed state, 2205 typically contains around 40-50% ferrite. Known as the go-to grade, UNS S31803 Pipe is the most widely used grade within the duplex family of stainless steels.

Duplex S32205 Seamless Welded Pipes can endure temperatures up to 572 degrees Fahrenheit. However, subjecting the pipes to temperatures exceeding this limit may result in their embrittlement. The chemical composition of these pipes imparts a high resistance to corrosion pitting and corrosion cracking, particularly at temperatures ranging from 302 degrees Fahrenheit. Additionally, the presence of a certain amount of ferrite in this alloy enhances the performance of these pipes, enabling their utilization in challenging environments. These pipes are particularly beneficial in areas prone to chloride-related stress cracking, as they exhibit excellent performance under such conditions.

Corrosion Resistance

Duplex Pipe offers a cost-effective solution for various applications where the susceptibility of 300 series stainless steels to chloride stress corrosion cracking is a concern. Chloride stress corrosion cracking occurs when stainless steels are exposed to tensile stress while in contact with chloride-containing solutions. It's worth noting that higher temperatures further increase the susceptibility of stainless steels to this type of corrosion.

The presence of chromium, molybdenum, and nitrogen in Duplex Steel 2205 imparts excellent resistance to chloride pitting and crevice corrosion. This resistance is particularly crucial for environments such as marine settings, brackish water conditions, bleaching operations, closed-loop water systems, and certain food processing applications. With its elevated levels of chromium, molybdenum, and nitrogen, Duplex Steel 2205 demonstrates superior corrosion resistance compared to common stainless steels like 316L and 317L in most environments.
