Duplex 2205 Stainless Steel Possible Alternative Grades
Given below is a list of possible alternative grades, which may be chosen in place of 2205.
Table 5 - Grade specification comparisons for 2205 grade stainless steels
|
Grade
|
Reasons for choosing the grade
|
|
904L
|
Better formability is needed, with similar corrosion resistance and lower strength.
|
|
UR52N+
|
High resistance to corrosion is required, e.g. resistance to higher temperature seawater.
|
|
6%Mo
|
Higher corrosion resistance is required, but with lower strength and better formability.
|
|
316L
|
The high corrosion resistance and strength of 2205 are not needed. 316L is lower cost.
|
Duplex 2205 Stainless Steel Corrosion Resistance
Grade 2205 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. Grade 2205 stainless steels are apt replacements to austenitic grades, especially in premature failure environments and marine environments.
Material summary and usage
S31803 steel is ultra-low carbon dual- phase stainless acid resistant steel. It is provided with excellent pitting corrosion and crevice corrosion resistant performances. In addition, nitrogen, as a strong element that forms and stabilizes austenite, still ensures the existence of certain amount of austenite in the structure even if after welding or heating under high temperature, and makes it difficult to form single-phase ferrite. The dual-phase proportion is not sensitive to the change of heating temperature.
