What Is Duplex 2205 Stainless Steel?
Duplex 2205 (EN 1.4462) also known as Duplex 2205 Stainless Steel, URANUS 45N, FALC223 with UNS S31803 and UNS S32205 is a two-phase corroded metal, ferritic and austenitic steel with 22% chromium (22Cr Duplex) 3% molybdenum, 5 to 6% nickel alloyed stainless steel also known as x2crnimon22-5-3 used extensively in applications that require good corrosion resistance & strength. Duplex 2205 (UNS S31803 / UNS S32205) also known as 1.4462 Duplex is a non-standard and popular grade of Stainless Steel. Thus, Duplex 2205 must be procured only from trusted vendors like Oshwin Overseas. Duplex 2205 also is known as Sandvik SAF 2205 / SAF 2205 is a Sandvik-owned trademark. FALC 223 is a trademark of KRUPP STAHL AKTIENGESELLSCHAFT.
Duplex 2205 Stainless Steel Composition
Duplex 2205 is a typical composition of 22% Chromium and 5% Nickel. 2205 Duplex Stainless Steel is a cheaper alternative to high nickel-based alloys due to low nickel composition.

Duplex 2205 Stainless Steel (1.4462) corrosion resistance is superior to Grade 316 in most environments. Heat treatment of Duplex SS 2205 is solution treatment (annealing), between 1020 – 1100°C, followed by rapid cooling. 2205 Duplex Stainless Steel (2205 Duplex) cannot be hardened by heat treatment. They can, however, be work hardened. The Duplex SS (Duplex 2205) stainless steel has undergone a number of modifications resulting in S32205 (Duplex 2205). 2205 Stainless Steel (Duplex Stainless Steel) offer higher resistance to corrosion. Duplex Steel (2205 Duplex) cannot be hardened by thermal methods. The density of Duplex SS is 7.805 g/cm³. Duplex Stainless Steel (2205 Duplex) Hardness is Max 31 HRC.
Duplex 2205 Stainless Steel Microstructure
The Microstructure of Duplex 2205 Stainless Steel (1.4462) shall be examined after solution heat treatment at a minimum of 400X magnification, and verified to be free from grain boundary particles (carbides, nitrides) and intermetallic phases (sigma, chi and laves), as defined by ASTM A923 Method A. A photomicrograph (x400) can be provided if requested. Machining Duplex Stainless Steel is low due to its high strength. The cutting speeds are almost 20% lower than that of grade 304. PREN number for 22 Cr Duplex Stainless Steel is between 35-40.
Duplex 2205 Welding
Duplex 2205 stainless steel has good weldability. Duplex Stainless Steel Welding Procedure includes all standard welding processes like Shielded metal arc welding (SMAW), Gas tungsten arc welding TIG (GTAW), Gas metal arc welding MIG (GMAW), Flux-cored arc welding (FCW), Plasma arc welding (PAW), Submerged arc welding (SAW), Laser welding, Resistance welding, High-frequency welding, etc. Duplex 2205 is very hard and difficult to manufacture.
