1. Test the authenticity of 304 stainless steel through stainless steel detection agent. Different stainless steel products will display different colors when encountering stainless steel detection agent. Therefore, it is more accurate and standard to distinguish whether 304 stainless steel is real or not through different colors. practice.
2. Use magnetism to judge whether 304 stainless steel is true or not. 304 stainless steel is weakly magnetic, so when using a magnet to attract magnetic 304 stainless steel, it will show weak magnetism, so to distinguish whether 304 stainless steel is true or not.
3. Use copper sulfate to detect, and use copper sulfate to wipe off the steel with the oxide layer. If it does not change color after rubbing, it can generally be judged stainless steel, but if it turns purple, if there is no magnetism, it is high manganese steel, and it is magnetic. Usually ordinary steel or low alloy steel.
