In the identification of high-grade hardware furniture, mainly divides into two parts, the part is to determine whether a furniture materials used for stainless steel, the other part is the material of stainless steel furniture. High-grade hardware furniture and some features are related to stainless steel, now a lot of manufacturers in order to seek high profits, with some other material imitation stainless steel, many don't understand the customer is hard to distinguish from the outside. Stainless steel furniture also is divided into two kinds of models 304 and 201, some 304 more expensive, and the corresponding service time is long, beautiful. These will make criminals to gaming. So understanding how to identify high-grade hardware furniture is an important thing.

1, high-grade hardware furniture is for stainless steel, the better identify some, believe a lot of people, with a magnet. This is just a rough identification way because chromium nickel stainless steel under the conditions of annealing and no magnetic, but after cold working is magnetic. We need to do is first through the way of sulfur, brass, stainless steel furniture drip a drop of water on the surface, then wipe the surface with sulfur brass, if you don't change color, is the stainless steel.

2, high-grade hardware furniture is 304 or 201 that are need tools to identify, now on the market has a lot of sell stainless steel testing potion. Water droplets on the surface of the stainless steel furniture that clean medicine, then place the battery cathode in drip into the potion ( Be careful not to come into contact with the stainless steel) , the anode is connected to the stainless steel, after the drip and electricity, different material will show different color, concrete the potion specifications shall prevail. Another is not electricity, drops of medicine water directly, if turned into a brown one second to say the material is 201. If drop in more than 50 seconds 304 slowly become weak gray, there will be a different length and color, the main reason is that 304 is not easy to oxidation.
