Perfect for scrap yard sorting
This liquid makes it incredibly easy to distinguish between 304 and 316 steel. The color change is distinct and happens quickly. Great value for the number of tests included.

Works as described
I use this in my small fabrication shop. It accurately identifies the manganese content differences. Just make sure to follow the instructions carefully for best results.

Reliable identification tool
Been using this for months now. Never had a false positive. The bottle lasts a long time since you only need a drop or two per test.

Essential for metal recyclers
Saves us from misidentifying expensive alloys. The 200-test capacity is accurate, and the reagent remains stable over time if stored properly.

Good but requires practice
The product works, but interpreting the shade difference took me a few tries to get right. Once you get the hang of it, it is very useful.
Q: What is the shelf life of this solution?
A: When stored in a cool, dark place with the cap tightly sealed, the solution typically remains effective for up to 2 years.
Q: How much liquid is needed for a single test?
A: Only one or two drops are required per test site, which is why one bottle provides approximately 200 uses.
Q: Is the liquid hazardous to skin contact?
A: Yes, it is a chemical reagent. We strongly recommend wearing protective gloves and eye protection during use and washing hands immediately after.
Q: Can this detect other metals like aluminum or copper?
A: No, this specific reagent is formulated solely for identifying manganese content to differentiate between 304 and 316 stainless steel grades.
Q: Does this work on painted stainless steel surfaces?
A: No, the surface must be clean and free of paint, oil, or rust for the reagent to react correctly with the metal.
