Super duplex material is stronger and more durable than regular duplex stainless steel. It has a special structure that makes it highly resistant to corrosion. Super duplex pipes contain more nickel, which makes them more expensive. This material can withstand acids, chlorides, and caustic solutions. It also offers better resistance to stress corrosion cracking and mechanical wear than standard stainless steel or regular duplex alloys.
The critical crevice temperature (CCT) is the temperature at which crevice corrosion becomes a problem. For super duplex stainless steel pipes, this temperature ranges from -50°C to 70°C. However, the exact critical crevice temperature (CCT) can vary based on the type of duplex steel, the heat treatment used, and the environment where the material is used.
