هل لديك أي فكرة عن كيفية تمييز ألواح الفولاذ المقاوم للصدأ؟

201 stainless steel and 304 stainless steel are the most commonly used stainless steel in water bottle production. And we’ll show you the method of distinguishing different stainless steel materials.

There are four stainless steel plates on our desk. Could you tell us which ones are 201 stainless steel and which ones are 304 stainless steel?

Now we have the answer.

201 stainless steel and 304 stainless steel differ in appearance. Compared with 304, the surface of 201 stainless steel shows a light yellow, while 304 is more silver, and 304 has better luster.

Then we will use professional potions to show you the difference in specific materials. As shown, potion color changes when we drop it on various materials. The better the material, the purer the color of the potion.

Firstly, we drop the potion onto the stainless steel plates, then wait for about 3 minutes.

Now, we can see the color changes clearly. The color of 201 stainless steel plates turned into light orange while 304 stainless steel remained unchanged.
