Duplex 2205(UNS S31803/UNS S32205/1.4462) stainless steel exhibits excellent corrosion resistance, much higher than that of grade 316. It resists localized corrosion types like intergranular, crevice and pitting. The CPT of this type of stainless steel is around 35°C. This grade is resistant to chloride stress corrosion cracking (SCC) at temperatures of 150°C. Duplex 2205 stainless steels are apt replacements for austenitic grades, especially in premature failure environments and marine environments.
The high oxidation resistance property of Duplex 2205 is marred by its embrittlement above 300°C. This embrittlement can be modified by a full solution annealing treatment. This grade performs well at temperatures below 300°C.
The best-suited heat treatment for this grade is solution treatment (annealing), between 1020 – 1100°C, followed by rapid cooling. Duplex 2205 can be work hardened but cannot be hardened by thermal methods.
The machinability of this grade is low due to its high strength. The cutting speeds are almost 20% lower than that of grade 304. The fabrication of this grade is also affected by its strength. Bending and forming of this grade requires equipment with larger capacity. Ductility of Duplex 2205 is lesser than austenitic grades; therefore, cold heading is not possible on this grade. In order to carry out cold heading operations on this grade, intermediate annealing should be carried out.
Some of the typical applications of duplex steel Duplex 2205 are oil and gas exploration, processing equipment, transport, storage and chemical process, high chloride and marine environments, paper machines, liquor tanks, and pulp and paper digesters.
Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchenware.

1.Corrosion Resistance: 2205 stainless stands-up excellently in a range of atmospheric environments even when exposed to corrosive elements, specifically to sea water.
2.Heat Resistance: Generally, 2205 is not suitable for use at temperatures above 300°C as it suffers from precipitation of brittle micro-constituents.
3.Avoid temperatures below -50°C because of its ductile-to-brittle-transition.
4.Easy to weld with excellent weldability.
5.The high strength of 2205 also makes bending and forming more difficult.
1.Not easily rust, acid resistance and corrosion resistance;
2.Widely used in light industry,heavy industry, daily necessities and the decoration industry;
3.Large and stable supplies, long-term supplies;
