Stainless steel decorative pipes are durable and not easy to rust, which just meets the needs of the public. Among the many stainless steel models, 304 stainless steel decorative pipes and 201 are widely used. When we buy stainless steel decorative pipes in our daily life, some unscrupulous merchants will sell 201 stainless steel decorative pipes as 304 stainless steel decorative pipes to obtain greater benefits. Today, I will share with you how to distinguish 304 stainless steel decorative pipes from 201 stainless steel decorative pipes with the naked eye.
1. Observe the surface brightness
It can be observed from the naked eye that the 304 stainless steel tube has a good luster and a smooth touch. The 201 stainless steel tube is dull in color and feels rough and not smooth to the touch.
2. Inspection of medicinal water
Apply stainless steel pickling agent to two kinds of stainless steel decorative pipes respectively. After 2 minutes, watch the color change of the stainless steel decorative tube where it is applied. The color is white or does not change color is 304 material, and the stainless steel decorative tube of 201 material will be black.
3. Grinding with a polisher
Two kinds of stainless steel decorative tubes can be lightly polished with a grinding wheel on a sander. When grinding, the spark of 304 stainless steel pipe is shorter, thinner and less. The spark of 201 stainless steel pipe is longer, thicker and more. The grinding force must be light, and the two grinding forces are the same, which is easy to distinguish.
4. The real standard stamp
Choose a stainless steel pipe manufacturer with a good reputation, such as a good stainless steel decorative pipe with a real standard stamp on the pipe body, you can clearly see the words "201" and "304", and attach an anti-counterfeiting label to prevent counterfeiting.
Summary: It is important to choose a stainless steel pipe brand manufacturer. I believe that stainless steel pipe brands that have been operating for many years will not smash their own signs for a little profit. I hope the above points can help you when choosing stainless steel decorative pipes.
