How to Select Stainless Steel plate
The construction industry is inseparable from stainless steel plates. Stainless steel plate has good corrosion resistance performance, so now many steel plate manufacturers are increasing the production of stainless steel plate. But there are also some illegal vendors, and they only pursue benefits but ignore the quality of stainless steel plates. Below we will introduce several stainless steel plate selection methods.
1. When selecting stainless steel plate, we should consider its uses and application environment. For example, the welded pipe is generally used for decoration; seamless pipe is usually used for fluid transport; for medical or kitchen, we often use sanitary grade stainless steel plates. Generally, 200 series stainless steel materials are used indoors, 304 materials are used outdoors, however, 316 materials and others are generally used in acidic, alkaline places or coastal areas.
2. Make sure the material is qualified. Take 304 as an example
a. From the price analysis, if 304 stainless steel plate is even lower than the prevailing price of 301 material on the market, you should be careful to identify it, and it is probably some other materials.
b. Identify whether the pipe surface is stamped with steel seal 304, and ask for qualifications and certifications as proof;
c. Run acid reagent test; After 30 seconds, material 304 will not change color, and 201 will turn black
d. For bulk purchase, you can take samples to the national authority testing center for composition testing.
3. Check whether the color of the outer surface and the inner wall of the tube is bright and smooth and whether the thickness is uniform or rough.
4. It is inevitable that the hot galvanized pipe sometimes has a pitting surface, but it basically does not affect the use, but it is better to check carefully and choose the less one, especially check the inner surface.
5. Be sure to choose a famous brand or visit the factory.
