🔩 1-Drop Stainless Steel Test Solution This quick and easy test reagent lets you identify stainless steel grades in seconds. With just one drop, it reacts differently to 200, 201, 301, 304, and 316 stainless steel, providing instant color-coded results for household and industrial use. ⚡ Instant, Color-Coded Results The solution reacts with the metal to produce distinct color changes based on the grade: deep red for 200/201, light purple for 301, and green for 304/316. The included color chart makes identification simple and reliable. 🏠 Household & Commercial Use Perfect for testing kitchenware, cookware, utensils, appliances, and tools. It helps verify the quality of stainless steel products, ensuring you’re getting the grade you paid for, whether for home use or business. 🧪 Safe & Easy to Use The dropper bottle allows for precise application, with no complicated equipment required. Simply clean the metal surface, apply one drop, and observe the color change. The test is non-damaging and leaves no permanent marks. ✅ Verifies Nickel Content & Corrosion Resistance The test works by reacting with nickel content in the steel, which determines its corrosion resistance. This helps identify whether the metal is low-grade (200/201) or high-quality (304/316), ideal for preventing rust and ensuring safety.
