CORROSION RESISTANCE Alloy 2205 boasts excellent resistance to chloride-induced pitting and stress corrosion cracking, making it a reliable choice for challenging environments.
ELEVATED TEMPERATURE RESISTANCE The ASME Boiler and Pressure Vessel Code sets an upper-temperature limit of 600°F (315°C). Extended exposure to higher temperatures can lead to embrittlement.
MECHANICAL PROPERTIES Alloy 2205 surpasses conventional austenitic stainless steels with more than twice the strength in the annealed condition. It is also available in a cold-worked condition with a yield strength exceeding 160 ksi, maintaining good toughness even at temperatures as low as -50°F (-10°C).
WORKABILITY Alloy 2205 is highly formable through cold forming. Due to its high work-hardening rate, intermediate annealing may be necessary. Post hot or cold forming, annealing is recommended to achieve optimal stress corrosion resistance.
Our forming capabilities are unmatched, featuring advanced extrusion and cold working assets for tube and pipe manufacturing. We boast one of the world's largest pilger mills and a unique hydroforming process for precision fittings.

Duplex 2205 stainless steel pipe is a remarkable duplex ferritic-austenitic stainless steel alloy, featuring 22% chromium, 3% molybdenum, and 5-6% nickel. As the most widely utilized duplex stainless steel grade, it offers twice the yield strength of standard austenitic grades. Renowned for its superior fatigue strength, it excels in resisting stress corrosion cracking, crevice, pitting, erosion, and general corrosion even in the most severe conditions.
Most manufacturers recommend a maximum hot forming temperature range between 2010 and 2100°F (1100 and 1150°C). If the workpiece lacks compactness, the edges may be significantly cooler than the bulk, increasing the risk of cracking in cooler areas.
The Duplex 2205 Stainless Steel Tube offers exceptional formability across various manufacturing processes. However, its high strength, while beneficial, requires consideration due to the increased springback effect. Ensuring that equipment is sufficiently powerful is crucial to manage this grade's specific demands.
Duplex 2205 presents slightly more machining challenges compared to the 300 series austenitic stainless steels. The increased cutting forces lead to faster tool wear. For optimal results, adhere to these guidelines: A) Utilize a robust, rigid machine with secure tool and workpiece mounts; B) Minimize tool extensions to reduce vibration; C) Maintain a minimal tool nose radius to ensure sharpness without compromising strength; D) Sequence machining to keep the depth of cut below the work-hardened layer from the prior operation.
