EASY TEST
inox
ELECTROCHEMICAL TESTER FOR STAINLESS STEEL
EASY TEST has been designed and manufactured to identify the typology of stainless steel through simple
tests:
1. magnetic test (it identifies stainless steel aisi 400 series);
2. test with manganese reagent (it identifies stainless steel - aisi 200 series to aisi 300 series);
3. test with molybdenum reagent (it identifies stainless steel aisi 304 series to aisi 316 series).

1. Magnetic Test
Aisi 400 series stainless steel are magnetic steels: to distinguish them it is enough put the magnet on
refill’s cover next to the metal (Picture 1).
2. Test with manganese reagent
Aisi 200 and Aisi 300 series stainless steel can be recognized for their different concentration of
manganese: AISI 200: Mn = 5,5 ÷ 10,5% - AISI 300: Mn < 2%
A. Put a blotting paper on the metal you’re testing;
B. Put the retractile probe (4) on the metal and press downwards up to the refill crushes the blotting
paper against the metal and wait for 10 seconds (Picture 2);
C. Verify immediately the coloration of the blotting paper:
• Red/purple (Picture A)Æ stainless steel aisi 200 series;
• Yellow (Picture B) Æ stainless steel aisi 300 series.
3. Test with molybdenum reagent
Stainless steel aisi 304 and aisi 316 series can be distinguished as per the absence or the presence of
molybdenum: AISI 304: Mo = absent - AISI 316: Mo = 2 ÷ 3%
A. Before verify that the metal submitted to test is stainless steel aisi 300 series;
B. Pour some molybdenum reagent’s drops on the blotting paper used for previous test, in the
colored zone (Picture 3).
C. Verify the color of blotting paper after 1 minute:
• White (Picture C) Æ stainless steel aisi 304 series;
• Pink (Picture D) Æ stainless steel aisi 316 series.
