We often use stainless steel plates in construction and home decoration. Stainless steel plate is a material with strong anti-corrosion ability, so it is widely used, but when we choose stainless steel plate, if it is purchased as a fake product, its material The corrosion resistance is also very bad, so we need to pay attention to the selection method when buying stainless steel plates.
What are the methods to choose stainless steel plate
Nowadays, stainless steel plates are indispensable in construction and decoration. Stainless steel plates are steel plates with good anti-corrosion ability. Therefore, many steel plate manufacturers are now increasing the productivity of stainless steel plates, but there are also some illegal vendors. Just pursuing benefits is to ignore the quality of stainless steel plates. The following will introduce several methods of stainless steel plate selection by Hongyuan Huili Beijing stainless steel plate resellers.
1. Before selecting the stainless steel plate, it is necessary to consider the use of the stainless steel plate and the use environment. For example: Welded pipes are generally used for decoration, seamless pipes are generally used for fluid transportation, sanitary stainless steel plates are used in medical or kitchen, and thick-walled pipes are used under pressure. Generally, 200 series materials can be used indoors, and 304 and other materials are used outdoors. Generally used in acid and alkaline places or coastal areas.
2. The material must be up to standard when selecting steel pipes. Take 304 material as an example: a. From the analysis of price, if the 304 stainless steel plate is even lower than the general price of 301 material on the market, it must be carefully discriminated, it is likely that other materials are impersonating; b, whether the steel surface is stamped The material is "304", and the manufacturer's quality certificate is required as a voucher; c. It can be tested with acid reagents. After 30 seconds, the material 304 does not change color and 201 turns black; d. Samples can be sent to the national authoritative testing center for bulk purchase Ingredient laboratory test.
3. Check whether the color of the outer surface and the inner wall of the tube is bright and smooth, and the thickness is uniform or rough. Generally, this item does not need to be checked for welded pipes. Seamless steel pipes are produced by cold drawing or hot rolling. Improper operation in the production process is prone to uneven thickness and cracks on the pipe surface. Rough surfaces are generally seamless pipes. No polishing treatment is performed, and there is no special requirement on appearance without affecting the use.
4. When purchasing, you should choose the excellent products that have been assessed by the Bureau of Quality and Technical Supervision. The long-term use of testimony and good word of mouth among customers are the most direct and effective purchasing methods.
5. Inner rolled skins, pits, and rolled green lines often appear in rolled pipes. Generally, these are unavoidable and basically do not affect the use, but you must choose as few as possible when purchasing, especially check The inner surface.
Therefore, when we purchase stainless steel plates, we must remember that we cannot blindly pursue the low price of stainless steel plates and ignore the most important quality. Only high-quality stainless steel plates can make me more comfortable to use.
