Frequently Asked Questions
Q: Which stainless steel grades can this test liquid identify?
A: This stainless steel test liquid is designed to identify and distinguish between grades 304, 201, 202, and 301 stainless steel through a clear color-change reaction system based on manganese content analysis.
Q: How do I use the stainless steel test reagent?
A: Simply apply a single drop of the reagent onto the metal surface you want to test and observe the resulting color change. No prior chemistry knowledge or special equipment is needed — the color reaction provides a straightforward visual result within seconds.
Q: Is the stainless steel test liquid safe for use on kitchen tableware and cookware?
A: Yes, it is suitable for testing tableware, cookware, and cutlery. However, after testing, it is recommended to thoroughly wash the tested item with household detergent and rinse with hot water before use. Always test in areas that will not come into direct mouth contact, and preferably in inconspicuous spots, as the reagent may leave slight traces.
Q: How many tests can I perform with one 12ml bottle?
A: Because only a single drop is required per test, one 12ml bottle can support a large number of individual tests, making it a cost-effective solution for ongoing material verification in workshops, kitchens, or field inspections.
Q: Can this reagent be used in the field or on a job site?
A: Absolutely. The compact 12ml bottle weighs approximately 25g and is designed for portability, making it easy to carry to remote locations, construction sites, or confined spaces where quick stainless steel grade verification is needed.
