With the increasing improvement of stainless steel application technology, the application of stainless steel in decoration is becoming more and more extensive. Stainless steel decorations are not only durable, but also beautiful and elegant, thus attracting more people to use stainless steel as decorative materials.
But when buying stainless steel decorative materials, you should keep your eyes open, because the material you buy may be "Li Gui" rather than the real "Li Kui" - stainless steel. For the sake of profit, some "stainless steel" products are just coated with a layer of paint on the iron, which will rust even if they are not bumped, and many companies will use cheap materials as high-priced materials.
There are many varieties of stainless steel, 201, 304, 316L...their prices vary a lot. The biggest difference is corrosion resistance. 304 has the best corrosion resistance, and 201 has the worst corrosion resistance. Of course, the price difference is also very big.
Stainless steel of poor quality will discolor on the surface if used for a long time, increase the staining rate, be easily corroded, and breed bacteria.
It is also easy to distinguish the quality of stainless steel. Just buy a bottle of "stainless steel measuring fluid". It is also called "stainless steel testing solution", "manganese testing box", "manganese testing liquid", etc.
The test method is: keep the stainless steel surface clean and free of oil stains, remove the coating and drop a drop of measuring solution, observe the color change, compare the color of the stainless steel or the time it takes to turn red, and determine the model of the stainless steel.
Tips for decoration: identification of five types of stainless steel
After dropping the measuring solution, different stainless steels will have different reactions:
200 stainless steel (fake 201): It turns red in about 5 seconds. After 10 seconds, the red color will be the same as on the color chart.
201 stainless steel (authentic 201): It turns red in about 50 seconds, and the red color will be the same as on the color card.
202 stainless steel: turns red in about 1 minute.
301 stainless steel: It turns red in about 3 minutes. The color is very light, so look carefully.
304 stainless steel: No change in 3 minutes. The color may become darker, but there is no red color.
