Alloy 2205 Citizen Metals Pvt. ltd. Company has an extensive inventory of 2205 stainless steel plate in thicknesses from 3/16" through 3". The yield strength is about twice that of austenitic stainless steels, thus allowing a designer to save weight and making the alloy more cost competitive when compared to 316L or 317L.

GENERAL DUPLEX STAINLESS STEEL INFORMATION
2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength. The standard duplex S31803 composition has over the years been refined by many steel suppliers, and the resulting restricted composition range was endorsed as UNS S32205 in 1996. Duplex S32205 gives better guaranteed corrosion resistance, but for much of the Duplex S31803 currently produced also complies with Duplex S32205. 2205 is not generally suitable for use at temperatures above 300ºC as it suffers from precipitation of brittle micro constituents, nor below -50ºC because of its ductile-to-brittle-transition.

DUPLEX CORROSION RESISTANCE
Excellent general corrosion resistance; superior to Grade 316 in most environments. Excellent resistance to localized corrosion including intergranular, pitting and crevice corrosion; the CPT of 2205 is generally at least 35ºC. The grade is also resistant to chloride stress corrosion cracking (SCC) at temperatures of up to about 150ºC. Grade 2205 will often perform well in environments which cause premature failure of austenitic grades. It has better resistance to sea water then Grade 316.
DUPLEX HEAT RESISTANCE
Although 2205 has good high temperature oxidation resistance, this grade – like other duplex stainless steels – suffers from embrittlement if held for even short times at temperatures above 300ºC. If embrittled, this can only be rectified by a full solution annealing treatment. Duplex stainless steels are almost never used above 300ºC.
DUPLEX HEAT TREATMENT
Solution treatment (annealing) – heat to 1020ºC-1100ºC and cool rapidly. This grade cannot be hardened by thermal treatment, but does work harden.
Stainless steels are high-alloy steels. These steels are available in four groups that include martensitic, austenitic, ferritic and precipitation-hardened steels. These groups are formed based on the crystalline structure of stainless steels.
Stainless steels contain larger amounts of chromium in comparison with other steels and thus have good corrosion resistance. Most of the stainless steels contain about 10% of chromium.
Grade 2205 stainless steel is a duplex stainless steel whose design enables combining improved resistance to pitting, high strength, stress corrosion, crevice corrosion and cracking. Grade 2205 stainless steel resists sulfide stress corrosion and chloride environments.

Fabrication and Heat Treatment
Grade 2205 stainless steel is annealed at 1020-1070°C (1868-1958°F) and then water quenched.
Grade 2205 stainless steel is hot worked in the temperature range of 954-1149°C (1750-2100°F). Hot working of this grade stainless steel under room temperature is recommended whenever possible.
Welding methods recommended for grade 2205 stainless steel include SMAW, MIG, TIG and manual covered electrode methods. During the welding process, the material should be cooled below 149°C (300°F) between passes and preheating of the weld piece should be avoided. Low heat inputs should be used for welding grade 2205 stainless steel.
Grade 2205 stainless steel is difficult to form due to its high strength and work hardening rate.
Grade 2205 stainless steel can be machined with either carbide or high speed tooling. The speed is reduced by about 20% when carbide tooling is used.
Grade 2205 stainless steel is used in the following applications:
(Duplex stainless steel plate USE : Duplex stainless steel plate is often used for storage tanks. High corrosion and erosion resistance is a must for storage tanks, whether the designer wants to prevent leakage during desalinization, avoid contamination in pharmaceutical or food processing, or store chips as well as black and white liquor for the pulp and paper industry.)
