How to distinguish the authenticity of stainless steel trash

Stainless steel trash cans are widely used by people because of their advantages of corrosion resistance, beauty, generosity, and hygiene. Stainless steel pedal bin is one of the stainless steel products. So how to identify the authenticity of stainless steel at the time of purchase? Fucheng Metals Production Co., Ltd. of Jiangmen City is summarized as follows:

(1) "Stainless" stainless steel is not absolutely rustless, but rather it does not rust under certain conditions. The bulletin board reminds everyone that if they are used improperly and use it in an environment or condition that exceeds their corrosion resistance, they will naturally rust.
(2) The stainless steel used in the product is corroded and rusted. It may also be due to the unreasonable selection of the manufacturer. For example, the propaganda column indicates that the manufacturer chose inappropriate stainless steel grades for raw materials for its product use, and may also be a manufacturer's production and processing technology. But off. In addition, it is that manufacturers have indeed chosen counterfeit and inferior stainless steel raw materials that do not meet the authority standards of the relevant countries or industries on the market.
Of the five major stainless steels currently developed and applied in the world, only austenitic stainless steels (many 300 series and 200 series grades) are often non-magnetic (after processing or weak magnetic), and ferritic stainless steel (many 400 series) Duplex stainless steel, martensitic stainless steel, and precipitation hardened stainless steel all have magnetic properties. With or without magnetic properties, each stainless steel has its own characteristics and applicable range.
It is obviously not feasible to identify the true and false quality of stainless steel by sucking it with a magnet. Is there any other feasible and convenient method? The answer is yes. Herein, a simple method is described, that is, the use of a stainless steel assay liquid to identify or distinguish between the conditions of the steel under test by observing the color change characteristics of the test liquid in the dissolution of the steel being tested. “Color change” is often related to specific elements such as nickel (Ni), molybdenum (Mo), and manganese (Mn) in the steel being tested.
