Duplex 2205 Stainless Steel Coil

2205 stainless steel coil is a high-strength low-alloy corrosion resistant stainless steel (UNS S32205). It has been developed as a cost-effective alternative to the more expensive austenitic stainless steel coils and nickel alloys coils.


The alloy composition of 2205 contains molybdenum, chromium and nitrogen. The addition of molybdenum provides resistance to pitting and crevice corrosion in chloride environments. Chromium improves the corrosion resistance in sulfate environments, whereas nitrogen enhances its resistance to stress corrosion cracking.

Properties of 2205 duplex stainless steel

Standard: ASTM A240/A240M--01 chromium 2205 duplex stainless steel alloy is a 22%, 2.5% 4.5%-NI-n alloy composition Mo and duplex stainless steels. It has high strength, good toughness and good global and local resistance to stress corrosion.
2205 duplex stainless steel yield strength of austenitic stainless steel is twice times, this feature enables designers to design products reduce the weight, price advantage over the 316,317L. This alloy is suitable within the temperature range-50 ° F/600 ° f. Exceeding this temperature range of application, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.

Corrosion Resistance
Grade 2205 stainless steel exhibits excellent corrosion resistance, much higher than that of grade 316. It resists localized corrosion types like inter-granular, 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 steels are apt replacements to austenitic grades, especially in premature failure environments and marine environments.

Heat Resistance
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.

Heat Treatment
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.

Welding
Most standard welding methods suit this grade, except welding without filler metals, which results in excess ferrite. AS 1554.6 pre-qualifies welding for 2205 with 2209 rods or electrodes so that the deposited metal has the right balanced duplex structure.
Adding nitrogen to the shielding gas ensures that adequate austenite is added to the structure. The heat input must be maintained at a low level, and the use of pre or post heat must be avoided. The co-efficient of thermal expansion for this grade is low; hence the distortion and stresses are lesser than that in austenite grades.

Machining
The machinability of this grade is low due to its high strength. The cutting speeds are almost 20% lower than that of grade 304.
