With the garbage classification, outdoor stainless steel trash can has become a favorite. Stainless steel has high durability due to its resistance to weak corrosive media such as air, steam and water, and chemical corrosive media such as acid, alkali and salt. The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, not more than 1.2% at most, and the ω C (carbon content) of some steels is even lower than 0.03% (such as 00Cr12). The primary alloy element in stainless steel is Cr (chromium). Only when Cr content reaches a certain value, the steel has corrosion resistance. Therefore, the general Cr (CR) content of stainless steel is at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
As a widely used type of garbage can, the outdoor stainless steel garbage can has a beautiful appearance and is easy to clean and maintain. In public places, the appearance of stainless steel is often scrawled. However, an important feature of stainless steel is that it can be cleaned out, which is a significant feature of stainless steel over aluminum. The appearance of aluminum is simple, leaving traces, which are often difficult to remove. When finishing the surface of stainless steel, it should follow the texture of stainless steel, because some of the surface processing texture is unidirectional.
Outdoor stainless steel trash can is most suitable for hospitals or other areas where health conditions are crucial, such as food processing, catering, brewing and chemical industry. This is not only because it is easy to clean every day, but also because it sometimes uses chemical cleaning agents, and it is not easy to breed bacteria. The test shows that the function of this field is the same as that of glass and ceramics. The material characteristics of outdoor stainless steel garbage can make it very environmental friendly and recyclable. Because of this advantage, outdoor stainless steel garbage can is also a key energy-saving product.
In addition, although the same as stainless steel, 201 and 304 outdoor stainless steel trash can also have differences.
304 stainless steel is a kind of common stainless steel, which has good processing function and high endurance. It is widely used in industry, furniture decoration and food medical profession. 304 as a universal stainless steel, in order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium, more than 8% nickel content. Compared with 304, 201 stainless steel reduces the content of nickel and increases the content of manganese. It has certain acid and alkali resistance functions, high density, no bubble and pinhole in polishing. It is a high-quality material for producing all kinds of watch case and bottom cover of watch belt. It is mainly used for decoration pipe, industrial pipe and some shallow stretching products. The defect of this series of materials is that the chromium content of less than 18% and low nickel content can not reach the balance and form ferrite. Therefore, the chromium content of 200 series stainless steel is reduced to 13.5% - 15%, and in some cases to 13% - 14%. Its corrosion resistance can not be compared with 304 and other similar steels.
