Monel 400 Characteristics

1;Resistant to seawater and steam at high temperatures

2;Excellent resistance to rapidly flowing brackish water or seawater

3;Excellent resistance to stress corrosion cracking in most freshwaters

4;Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated

5;Offers some resistance to hydrochloric and sulfuric acids at modest temperatures and concentrations, but is seldom the material of choice for these acids

6;Excellent resistance to neutral and alkaline salt

7;Resistance to chloride induced stress corrosion cracking

8;Good mechanical properties from sub-zero temperatures up to 1020° F

9;High resistance to alkalis
