In our lives, many of the appliances are made of stainless steel, such as various pots and pans. At present, China Welded Stainless Steel Tubing is divided into many types, of which 304 stainless steel and 316 stainless steel is mainly used in our daily life. These two kinds of stainless steel are not the same, but the market is not clear on 304 stainless steel and 316 stainless steel. It is better to have the logo, but the logo is not necessarily true. Some merchants sell 316 stainless steel as 304 stainless steel. Light is not clear with the eyes, teach you 3 methods, simply distinguish 316 stainless steel.
SUS 316 Stainless Steel Tube
SUS 304 TB Stainless Steel Pipe and 316 stainless steel are different. Generally, 316 stainless steel has more Ni and Cr elements than 304 stainless steel. The hardness and oxidation resistance are better than 316 stainless steel. 316 stainless steel is better to use. One point is that the price of 316 stainless steel is more expensive in the market. When we buy these two kinds of stainless steel, we will find that some marks are not available. If we separately distinguish the two kinds of stainless steel, it is unclear, let alone Some merchants sell 304 stainless steel to 316 stainless steel, which is even more unclear. It teaches you three methods to easily distinguish 316 stainless steel.
When buying 316 stainless steel products, you can bring a magnet with you. It can be distinguished by 316 stainless steel and 304 stainless steel by a magnet. The magnetic properties of 316 stainless steel are lower than that of 304 stainless steel. It can be said that 316 stainless steel is not magnetic. If you find that stainless steel is very magnetic when you buy it, it maybe 304 stainless steel.
These two kinds of stainless steel can also be distinguished by the syrup method. Generally, 304 stainless steel is to use Ni8 syrup, 316 stainless steel is to use No2 syrup when distinguishing with syrup, it is necessary to observe the color change, and when using Ni8 syrup to distinguish 304 stainless steel The color turns red is 304 stainless steel and vice versa. When using No2 the solution to distinguish 316 stainless steel, the color turns red is 316 stainless steel, and vice versa, these can be purchased online.
3. Beat spectrum
The method of large spectrum is relatively professional. Each metal has its own spectrum. The spectrum of 304 stainless steel and SUS 316 Stainless Steel Tube is different. It can be easily distinguished by the spectral method, but this method is too professional. If you don't know much about this method, it is recommended to find a professional appraisal agency.
Due to prolonged exposure, the stainless steel tube will be dirty and even have some drawbacks, so it should be cleaned regularly. The effect of rain washing is determined by placing the same slats directly in the atmosphere and in a shed. The effect of manual rinsing is determined by manually scrubbing the right side of each slat every six months with a sponge dipped in soapy water. As a result, it was found that dust and deposition on the surface by rain washing and manual scrubbing had a good effect on the surface condition as compared with the slats placed in the shed and not washed. It has also been found that the condition of the surface finish is also affected, and the smooth-surfaced slats are better than the rough-surfaced slats. Therefore, the interval between washes is affected by many factors, the main influencing factors are the required aesthetic standards. Although many stainless steel curtain walls are only rinsed when the glass is being wiped, in general, the stainless steel for the exterior is washed twice a year.
