Duplex 2205 stainless steel is resistant to chlorides and H2S. Is a problem solver in most industry segments. Duplex 2205 is utilized in heat exchangers and piping in oil and gas, oil refinery, chemical, and petrochemical industry.
The design strength of 2205 is significantly higher than 316/316L, often permitting lighter wall construction. 2205 has good notch impact toughness down to temperatures below 40°F. Duplex is welded with E2209 or ER2209 fillers.
Grade 2205 stainless steel exhibits excellent corrosion resistance, much higher than that of grade 316. It resists localized corrosion types like an 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. Grade 2205 stainless pipes of steel are apt replacements to austenitic grades, especially in premature failure environments and marine environments.
The high oxidation resistance property of Grade 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. Grade 2205 can be work-hardened but cannot be hardened by thermal methods.
What is Duplex 2205?
Duplex 2205 is a type of stainless steel that belongs to the family of duplex stainless steels, which are designed to have a combination of high strength and excellent corrosion resistance. Duplex 2205 is composed of a mixture of austenitic and ferritic phases, providing superior mechanical and corrosion resistance properties compared to traditional austenitic stainless steels.
Duplex 2205 has several advantages over other types of stainless steel, including:
Excellent corrosion resistance: Duplex 2205 offers superior resistance to pitting, crevice corrosion and stress-corrosion cracking compared to traditional austenitic stainless steels.
High strength: Duplex 2205 has higher strength than most other types of stainless steel, particularly in terms of its yield and tensile strength.
Good weldability: Duplex 2205 can be easily welded using conventional welding techniques, without affecting the properties of the material.
Good machinability: Duplex 2205 is relatively easy to machine, despite being a duplex stainless steel.
Duplex 2205 is commonly used in various industries such as chemical processing, oil and gas, pulp and paper, and marine applications. It is particularly suitable for use in corrosive environments where high strength and good corrosion resistance are required.
Overall, Duplex 2205 is an important material that offers a combination of strength, corrosion resistance, and ease of fabrication, making it a popular choice for various industrial applications.
