Stainless steel plate selection tips
Stainless steel plates have a smooth surface, high plasticity, toughness and corrosion resistance, so they are widely used and have become a popular element in the current decoration industry. But we must also know how to distinguish when choosing stainless steel plates, because high-quality plates can not only increase the gloss of the product but also ensure the quality of the product. If we buy inferior plates, the performance of the material will also be greatly reduced, so when we buy stainless steel When choosing a board, you need to pay attention to the selection method.
Before choosing a stainless steel plate, you need to consider the purpose and use environment of the stainless steel plate. For example: food-grade stainless steel plates should be used in medical or kitchen; generally, 200 series materials can be used indoors, 304 and other materials should be used outdoors, and materials above 316 are generally used in acidic and alkaline places or coastal areas.
When selecting boards, you must make sure the materials meet the standards. 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 301 material on the market, you must carefully identify it, it is likely to be counterfeited by other materials; b. Identify whether the steel plate is stamped on the surface of the tube. "304" is printed on it, and the manufacturer's quality certificate must be obtained as proof; c. It can be tested with acidic reagents. After 30 seconds, the material 304 will not change color, and the material 201 will turn black; d. For bulk purchases, samples can be taken and sent to the national authoritative testing center for composition analysis Laboratory testing.
Check whether the color of the outer surface is bright and smooth, whether the thickness is uniform or rough.
When purchasing, you should choose excellent products that have been evaluated by the Quality and Technical Supervision Bureau. Having long-term use testimonials and good reputation among customers is the most direct and effective way to purchase.
Heavy skin, pitting, and rolling green lines often appear in rolled plates. Under normal circumstances, these are unavoidable and do not affect use. However, you must choose as few as possible when purchasing.
Be sure to choose big brand stainless steel, such as products from large state-owned steel plants such as Taiyuan Iron and Steel, Baosteel, and Jiugang.
Therefore, 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.
