Testing Procedures for Stainless Steel

Wolf from Coslow Scientific demonstrates the Passy Color Kit 1626, used to verify the passivation of stainless steel or titanium parts by detecting free iron. The video explains the importance of reading the instruction manual and following safety precautions, such as wearing eye protection and washing hands. The testing procedure involves applying a solution to stainless steel samples and using test paper to determine passivation. The video concludes with a recommendation for the Passy Flash 3036 for faster testing.

What is the primary purpose of the Passy Color Kit 1626?

• To polish titanium surfaces

• To verify the passivation of stainless steel or titanium parts

• To clean stainless steel surfaces

• To measure the thickness of metal parts

What is free iron in the context of stainless steel?

• Iron that is used in welding

• Iron that is used for coating

• Iron that is introduced to the surface during machining

• Iron that is part of the alloy

What safety precaution is emphasized before starting the testing process?

• Wearing a lab coat

• Using a face mask

• Using eye protection and washing hands

• Wearing gloves

What is the first step in evaluating stainless steel samples with the Passy Color Kit?

• Heating the sample

• Applying a couple of drops of solution

• Polishing the sample

• Weighing the sample

How long should you wait after applying the solution before using the test paper?

• 10 minutes

• 1 minute

• 30 seconds

• 5 minutes

What might indicate that a stainless steel sample is not passive?

• The sample is lightweight

• The sample is heavy

• The sample was abraded or has embedded free iron

• The sample is shiny

What should be done after completing the test with the Passy Color Kit?

• Leave the solution on the surface

• Wipe the surface clean to remove residual testing solutions

• Heat the sample

• Apply more solution

What is the Passy Flash 3036 used for?

• A device for measuring temperature
