Quality Discrimination Method Of 304 Stainless Steel Plate

1、 Observe the thickness of substrate and lamination

304 stainless steel plate is composed of substrate and colorful retroperitoneum or coating. We must first consider the thickness of substrate and retroperitoneal coating. The better 304 stainless steel plate substrate is 0.15 ~ 0.47mm, and the thickness of sub film or coating is often less than 0.16mm. Since it affects the service time of 304 stainless steel plate, the wall thickness of substrate is very important. Some manufacturers of 304 stainless steel plate usually use their hands and feet on the substrate and wear-resistant steel pipe 304 stainless steel plate coating or sub coating. They reduce the thickness of the substrate, but increase the thickness of the mucous membrane to reduce the product cost of 304 stainless steel plate, which greatly reduces the service life of 304 stainless steel plate.

2、 Observe the exposed edge of 304 stainless steel plate

After obtaining a 304 stainless steel plate, I will first check whether the exposed 304 stainless steel plate, such as the cross section, has fine crystal, whether it is gray, dark and residual. If the cross section is exquisite, the quality is relatively excellent.

3、 Listen to the sound

Knock 304 stainless steel plate with fingers or hard blocks. If the material is weak, the sound is dull. The sound of metal materials is not significant. The sound of metal materials with good materials is very loud and crisp.

4、 Query the quality standard confirmation of 304 stainless steel plate

Whether there are inspection standards of relevant departments. If possible, visit the manufacturer of 304 stainless steel plate as far as possible. Look at the company's natural environment and see if it's reliable. Ask about the company's reputation in the sales market.

5、 Look at the price

Everything is worth every penny. When we compare the quality of 304 stainless steel plate, the price is one aspect, but we don't have to pay too much attention to the price. If the price of a 304 stainless steel plate is much lower than others, we should pay attention to it.
