Standard industry tool
Nothing fancy, just a solid tool for quality control. The instructions were clear and easy to follow.

Fast and reliable
Got immediate results on a batch of pipes we were unsure about. Highly recommend for any fabrication shop.

Works well but needs care
The reagent works exactly as described. Just make sure to clean the surface thoroughly before applying, or the result might be skewed.

Essential for our scrap yard
We process tons of metal daily, and this liquid saves us from mixing up 304 and 316 grades. The color distinction is very clear.

Accurate identification
Used this to verify a supplier's claim on a large order. It correctly identified the manganese content difference between the grades.

Good product, small bottle
The testing liquid is effective, but the 20ml bottle runs out quickly if you are testing large quantities every day.
Q: Is this safe to use indoors?
A: It should be used in a well-ventilated area. While not highly volatile, standard industrial safety precautions including gloves and eye protection are recommended.
Q: Can I test painted surfaces?
A: No, the surface must be bare metal. You need to grind or sand off any paint, coating, or rust before applying the reagent for an accurate reading.
Q: Can this liquid be used on aluminum or only steel?
A: This specific reagent is formulated exclusively for distinguishing manganese content in stainless steel grades like 304 and 316. It is not suitable for aluminum testing.
Q: What colors indicate 304 versus 316?
A: Typically, a rapid darkening indicates higher manganese content associated with certain grades, while 316 shows a different reaction profile. Please refer to the included color chart for precise interpretation.
Q: Does the solution expire after opening?
A: Once opened, it is best used within 6 months for optimal accuracy, provided the cap is sealed tightly after each use and stored correctly.
