Duplex stainless tube & pipe represent a specialized category of stainless steel known for their dual- phase microstructure, combining both austenitic and ferritic phases. The duplex structure provides a potent combination of mechanical properties for these tubes, making it to offer higher strength than austenitic stainless steel while retaining good ductility and toughness. This attribute enables duplex tube & pipes to withstand challenging conditions, including high pressures and temperatures, without compromising their structural integrity. Widely used in a industrial applications requiring exceptional performance under harsh operating conditions.

    2205 stainless steel tube is the most widely used duplex (ferritic/austenitic) stainless steel. Because of its high chromium, molybdenum and nitrogen contents, duplex 2205 offers excellent general corrosion resistance and localised corrosion including intergranular, pitting and crevice corrosion. The grade is also resistant to chloride stress corrosion cracking at temperatures of up to about 150°C.

  • Ronsco,2507 Super Duplex Tube,1,4410 Super Duplex Tube,S32750 Super Duplex Tube
    The higher chromium and molybdenum content in 2507 stainless steel tube enhances its resistance to a broader range of corrosive environments, including highly acidic and chloride-rich settings. It is particularly renowned for its resistance to localized corrosion phenomena such as pitting, crevice corrosion, and stress corrosion cracking in chloride-containing environments. The super duplex 2507's ability to withstand harsh conditions, including chloride stress corrosion cracking at elevated temperatures exceeding 150°C, underscores its exceptional performance in aggressive industrial settings.

  • Ronsco,S32760 Duplex Stainless Tube,1,4501 Duplex Stainless Tube,F55 Duplex Stainless Tube
    S32760 stainless steel tube, classified as a duplex stainless steel, boasts exceptional resistance to corrosion from organic acids like formic and acetic acid, making it ideal for high-concentration and high-temperature applications where conventional austenitic stainless steels may corrode rapidly. Within specific concentration ranges, its resistance to inorganic acids rivals that of high-alloy austenitic stainless steels. Compared to other 25Cr-type duplex stainless steels, super duplex S32760 exhibits superior resistance to pitting and crevice corrosion. Additionally, it demonstrates outstanding resilience against chloride-induced stress corrosion cracking, erosion corrosion, and corrosion fatigue.
