CORROSION RESISTANCE Alloy 2205 is renowned for its excellent resistance to chloride-induced pitting and stress corrosion cracking.
ELEVATED TEMPERATURE RESISTANCE The ASME Boiler and Pressure Vessel Code sets an upper temperature limit of 600°F (315°C). Prolonged exposure to temperatures above this can lead to embrittlement.
MECHANICAL PROPERTIES Alloy 2205 offers more than double the strength of conventional austenitic stainless steels in its annealed state. It can also be supplied in a cold-worked condition with a yield strength exceeding 160 ksi, maintaining impressive toughness even at temperatures as low as -50°F (-10°C).
WORKABILITY Alloy 2205 can be cold formed, though its high work-hardening rate may necessitate intermediate anneals. Post hot or cold forming, annealing is recommended to achieve optimal stress corrosion resistance.
Our unmatched forming capabilities redefine excellence in tube and pipe manufacturing. Equipped with cutting-edge extrusion and cold working assets, we offer an unparalleled production experience. Highlighting our prowess, we boast one of the world's largest pilger mills and a distinctive hydroforming process that ensures precision fittings like no other.

Duplex 2205 stainless steel pipe is a duplex ferritic-austenitic stainless steel containing 22% chromium, 3% molybdenum, and 5-6% nickel. Renowned as the most commonly utilized duplex grade, it boasts a yield strength twice that of conventional austenitic grades. This material offers remarkable fatigue strength and excellent resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion even under severe conditions.
Manufacturers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the workpiece is not uniformly compact, there is a risk of cracking in the cooler areas.
Duplex 2205 Stainless Steel Tube showcases excellent formability across various manufacturing processes. However, its high strength can pose challenges. Even with robust equipment, the substantial springback characteristic of this grade must be carefully considered.
Duplex 2205 requires more effort to machine compared to 300 series austenitic stainless steels due to higher cutting forces, leading to faster tool wear. Key machining guidelines include: A) Employ a powerful, rigid machine with strong tool and workpiece mounts; B) Minimize tool extensions to reduce vibration; C) Maintain a minimal tool nose radius to keep the carbide edge sharp yet strong; D) Strategically plan machining sequences to ensure the cutting depth remains below the work-hardened layer from previous operations.
