Stainless Plate Selection Method
We often use stainless plates in construction and home decoration. Stainless plates are a kind of material with strong anti-corrosion ability, so they are very widely used. However, when we choose stainless plates, if we buy fake and inferior products, it’s material The anti-corrosion property is also very bad, so when we buy stainless steel plates, we need to pay attention to the selection method.
What are the ways to choose stainless steel plates?
Stainless steel plates are inseparable in current construction and decoration. Stainless steel plates are a kind of steel plate with good corrosion resistance. Therefore, many steel plate manufacturers are increasing the productivity of stainless steel plates, but there are also some illegal vendors. Pursuing interests only ignores the quality of stainless steel plates. Below, Hongyuan Huili’s Beijing stainless steel plate reseller will introduce several stainless steel plate selection methods.
1. Before selecting stainless steel plates, consider the purpose and use environment of the stainless steel plates. For example, Welded pipes are generally used for decoration, seamless pipes are generally used for fluid delivery, sanitary stainless steel plates are used for medical treatment or kitchen, and thick-walled pipes are used for pressure; generally, 200 series materials are used for indoors, and 304 materials are required for outdoor use. Generally, materials above 316 should be used in acid-alkaline places or coastal areas.
2. Make sure that the material meets the standards when selecting steel pipes. Take 304 material as an example: a. From the price analysis, if the 304 stainless steel plate is even lower than the general price of the 301 material on the market, you must carefully identify it, it is likely to be a counterfeit of other materials; b. Identify whether the pipe surface is stamped The material is “304”, and the manufacturer’s quality certificate must be obtained as a voucher; c. It can be tested with acidic reagents. After 30 seconds, the material 304 will not change color and 201 will turn black; d. If you buy in large quantities, you can take samples and send them to the national authoritative testing center. Component laboratory testing.
3. Observe whether the color of the outer surface and the inner wall of the tube is bright and smooth, whether the thickness is uniform or rough. Generally, welded pipes basically do not need to be inspected, and seamless steel pipes are produced by cold drawn or hot rolled methods. Improper operation in the production process is prone to uneven thickness and cracks on the pipe surface. The rough surface is generally a seamless pipe. No polishing treatment, if there is no special requirement on the appearance, it will not affect the use.
4. When purchasing, you should choose excellent products that have been assessed by the Bureau of Quality and Technical Supervision. Long-term use testimony and a good reputation among customers are the most direct and effective ways to purchase.
5. Internal heavy leather, pitting, and rolled blue lines often appear in rolled pipes. Under normal circumstances, these cannot be avoided and basically do not affect the use, but you must choose as few as possible when purchasing, especially checking The inner surface.
6. Be sure to choose big brands of stainless steel, such as Taiyuan Iron and Steel Stainless Steel, Baosteel Stainless Steel, and so on.
So when we buy 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.
