Dual phase steel 2205 and 2207 stainless steel perform well in many
applications, but there are still some key differences between them. Here are
some main differences:
Strength and hardness
The strength and hardness of 2207 duplex stainless steel are usually higher
than 2205, which makes it more advantageous in situations where it needs to
withstand larger loads. High strength and hardness make 2207 perform well in
many demanding applications.
Corrosion resistance
Both have excellent corrosion resistance, but in certain specific
environments, 2207 performs even better. Due to its higher content of molybdenum
and nickel, 2207 exhibits better resistance to pitting corrosion, crevice
corrosion, and uniform corrosion, especially in environments containing chloride
ions. Its corrosion resistance far exceeds that of ordinary stainless steel.
Processability
In terms of processing and forming, 2205 duplex stainless steel is relatively
easier and has a lower degree of work hardening. Due to its high strength and
hardness, 2207 may require higher energy and finer process control during
processing.
Overall, the choice of stainless steel depends on specific application
requirements and environmental conditions. If you need a material that is both
corrosion-resistant and easy to process, 2205 may be a better choice. If you
need higher strength and corrosion resistance, especially in harsh environments,
then 2207 may be more suitable for your needs
