We know that stainless steel is relatively expensive among steel materials, so the difference between good and bad stainless steel is very important. 304 stainless steel can be seen everywhere in our lives. For example: many tableware, thermos cups, furniture, railings, medical equipment, water tanks, etc. are made of stainless steel. Today I will talk about how to distinguish the quality of stainless steel from bad.

 
How to distinguish between good and bad stainless steel

1. The quality of stainless steel can be seen through its surface color and smoothness to the touch.

2. Stainless steel can be judged through steel inspection potion. For example: 304 stainless steel will not change color in about 5 minutes after passing the liquid test; 201 stainless steel will instantly turn dark brown or red after the liquid drops; 202 stainless steel will quickly turn into light brown red after passing the liquid; and 304 stainless steel is not very magnetic. We can also try it with a magnet. If it is attracted by the magnet, it also means that 304 stainless steel is impure.

3. It depends on its weight. A heavy one will sound thick and full, on the contrary, a light one will sound cracked.

4. The types of stainless steel are different. The alloy containing titanium is white and shiny, and the alloy containing manganese is golden and black.

 
Here we focus on 304 stainless steel, which is a general-purpose stainless steel material with strong rust resistance, high temperature resistance, and corrosion resistance. Therefore, 304 stainless steel products can be seen everywhere in our lives. Through the editor's distinction between good and bad stainless steel, can you distinguish between good stainless steel and inferior stainless steel?
