304 mesh is widely used in the stainless steel market. Many European and American countries buy the most. Why is the 304 screen so popular, what is the reason?
The 304 wire mesh contains a chromium-nickel stainless steel, and the 304 wire mesh has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Corrosion resistant in the atmosphere, if it is an industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion. Suitable for processing, storage and transportation of food. Has good processing properties and weldability. Plate heat exchangers, bellows, household goods, building materials, chemicals, food industry, etc.
304 screen inspection
1. Test with acidic reagent. After 30 seconds, the material 304 stainless steel product does not change color, and 201 stainless steel product turns black.
2. Identify whether the stamped material “304 or 0Cr18Ni9” is printed on the pipe surface, and ask for the manufacturer's quality certificate and quality guarantee certificate.
3. Look at the outer surface, such as the inner wall of the stainless steel tube, whether the color is bright and smooth, the thickness is uniform, or there is a rough phenomenon.
4, can be tested by spectroscopy
