CORROSION RESISTANCE Alloy 2205 offers superior resistance to chloride-induced pitting and stress corrosion cracking, ensuring reliability in demanding conditions.
ELEVATED TEMPERATURE RESISTANCE The ASME Boiler and Pressure Vessel Code places an upper-temperature limit of 600°F (315°C). Exposure to temperatures above this for extended periods leads to embrittlement, impacting material integrity.
MECHANICAL PROPERTIES Alloy 2205 boasts more than double the strength of conventional austenitic stainless steels in the annealed condition. It can also be provided in the cold-worked condition, with yield strength exceeding 160 ksi, maintaining good toughness even at temperatures as low as -50°F (-10°C).
WORKABILITY Alloy 2205 can be cold-formed, though it has a high work-hardening rate, necessitating intermediate anneals. Annealing is also recommended after hot or cold forming to achieve optimal stress corrosion resistance.
Our forming capabilities are unrivaled, 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, ensuring world-class quality and performance.

Duplex 2205 stainless steel pipe is a high-performance duplex ferritic-austenitic stainless steel composed of 22% chromium, 3% molybdenum, and 5-6% nickel. This widely utilized duplex stainless steel grade boasts a yield strength double that of regular austenitic grades. Renowned for its excellent fatigue strength, Duplex 2205 excels in resisting stress corrosion cracking, crevice, pitting, erosion, and general corrosion, even under severe conditions.
Most manufacturers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 and 1150°C). If the workpiece is not uniform, the edge may cool faster than the bulk, increasing the risk of cracking in the cooler areas.
The Duplex 2205 Stainless Steel Tube showcases exceptional formability across a diverse range of manufacturing processes. However, its high strength can pose challenges, necessitating powerful equipment. Additionally, the significant springback characteristic of Duplex 2205 requires careful consideration during processing.
Duplex 2205 presents a higher machining challenge compared to 300 series austenitic stainless steels due to higher cutting forces and accelerated tool wear. Here are some expert machining guidelines: A) Employ a powerful, rigid machine with robust tool and workpiece mounts; B) Minimize tool extensions to reduce vibration; C) Ensure the tool nose radius is just sufficient to maintain a sharp edge and provide adequate strength; D) Sequence machining operations so that each depth of cut remains below the work-hardened layer from prior operations.
