2205 Duplex Stainless Steel Pipe Description
2205 duplex stainless steel pipe combines austenitic and ferritic structures, offering superior strength and corrosion resistance. With high chromium, molybdenum, and nitrogen content, it provides excellent resistance to pitting, stress corrosion cracking, and crevice corrosion, making it ideal for applications in marine, chemical, and oil & gas industries. The high strength of 2205 duplex stainless steel allows for reduced material thickness without sacrificing durability. Additionally, it exhibits outstanding weldability, toughness, and resistance to high-temperature oxidation. This makes 2205 duplex stainless steel pipe an optimal choice for demanding environments requiring both strength and corrosion resistance.
