Passi-Color Kit 1626


Part No. 1626

Applications: Detects Surface Free Iron on Stainless Steel and Titanium


  • Detects Surface Free Iron on Stainless Steel and Titanium
  • Tests for surface free iron on all stainless steels and titanium alloys
  • Stable solutions, no need to mix solutions before testing
  • 200 tests per kit
  • Fast, easy, reliable results

Free iron or unalloyed iron remaining on the surface of stainless steel after machining, milling, drilling etc; can lead to corrosion. Surface free iron is detected by a simple 2 minute color spot test. Whole surfaces can be spot tested. This test is also recommended for testing the inside bore of small tubes such as hypodermic needles and HPLC tubes. The Passivation Test Kit 1626 is faster and much more convenient than any chemical test in the ASTM spec A 967-96.

Reliable and simple to use
by Cameron Bendian, Jun 27,2019

This kit has been very helpful for over 2 years now, and Koslow offers good technical support as well. The pink color is very pigmented so it is easy to tell the results, and simple to use! I would highly recommend this product.
