SURFOX Test
4.3 Test with molybdenum reagent (page 4, D)
Stainless steel AISI 304 and AISI 316 series can be distinguished as per the
absence or the presence of molybdenum in their chemical composition:
Once you checked that the tested metal belongs to the AISI 300 series with the
SURFOX TEST, it is possible to establish the eventual presence of molybdenum
in steel by a simple chemical test.
Test:
1. Verify by SURFOX TEST that the metal submitted to test is stainless steel
AISI 300 series (par 4.2);
2. Pour some electrolyte's molybdenum reagent's drops (12) on the blotting
paper used for previous test, in the colored zone (D);
3. Verify the color of blotting paper after 1 minute from the beginning of
the chemical reaction:
• White g Absence of "Mo" g stainless steel AISI 304 series.
• Pink g Presence of "Mo" g stainless steel AISI 316 series.
Note: When the molybdenum reagent is put on the blotting paper, a chemical
reaction starts immediately: the blotting paper's color will become Maroon Red
for a moment and then it will turn white or pink after only 30 - 60 seconds.

5. Disposal and scrapping

Note: Seal the refill (5) inside the tester using the plastic cap (2), in order to
reduce the evaporation of the electrolytic solution contained.
Packing: This waste is similar to the urban kind.
Spent blotting papers and refill: The disposal of special waste must be in
compliance with the regulations in force.
Obsolete tools: With reference to CE2002/96 directive (WEEE), the user must
separate the electrical and the electronic components and dispose of them in
the appropriate authorized collection centers or give them back to the seller,
where a new purchase was made.
