It seems that with 304 the color doesn't change, but based on what it says in the instructions, the color may not change for other types of metal as well. That makes this a poor test for anything other than 316 testing, which unfortunately is not what I need since I'm trying to test for 304. Now the only thing I know for certain about the metal I'm testing is that it's not 316 Stainless, but since it's also not magnetic, I assume it's 304. The point of the test was to confirm this. ## Frequently Bought Together - Stainless Steel Test Kit for Differentiating 316/304 [Packaging Upgraded 2025] - DIYMAG Super Strong Neodymium Fishing Magnets, 500 lbs(227 KG) Pulling Force Rare Earth Magnet with Countersunk Hole Eyebolt for Retrieving in River and Magnetic Fishing,Diameter 2.36 inch(60 mm) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/577383394-stainless-steel-test-kit-for-differentiating-316-304-packaging-upgraded](https://www.desertcart.tn/products/577383394-stainless-steel-test-kit-for-differentiating-316-304-packaging-upgraded) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-30*
