Description
This kit verifies if the surface is passive and if it will resist oxidation as requested by steel specifications for AISI 300 and 400. It can also be used to quickly separate Series 400 from Carbon steel.
This test will give a red/pink result when in contact with Iron. The chemicals used in these tests are not hazardous. But the surface should be carefully rinsed after the test.
