Can I use material as CS for DM water with 90 ppmw TDS and high condutivity?

Generally SS should be used. DM water is often called as hungry water as it rarely contains minerals and this will lead to corrosion of CS. This will also lead to degradation of the quality of the water because of corrosion products.

 

So wherever there is a stagnation of water e.g. storage tank better go for SS or epoxy coating at the inside of the tank.

 

You need to discuss this with the Materials Engineer, this would be an easy for him.
