Describe the method of testing for checking of MOC of SS material (Molybdenum test)?

Procedure:

1.   Put one drop of the electrolyte solution of molybdenum test kit on the clean metal surface, which is to be tested.

2.       Switch on the detector and touch the metal tip of the detector on the metal surface & carbon point in the electrolyte solution.

3.       Do not pass the current for more than 3 to 4 seconds.

4.       If the red color appears and is stable for more than 2 seconds then it can be concluded that MOC of the part being tested is SS-316.

5.       If the solution remains colorless or green color appears then it can be concluded that MOC of the part being tested is SS-304.

6.       If the black color appears & is stable for more than 2 seconds then it can be concluded that MOC of the part being tested is SS-302.
