Stainless steel is one of the materials that is often counterfeited. In order to reduce production costs and increase profits, some units often produce metal products, but the quality is often poor, and may even include impurities and not be coated with quality films. During the sales process, stainless steel suppliers need to verify the origin of the material, and buyers also need to have complete knowledge of the characteristics of stainless steel to be able to distinguish real stainless steel from fake stainless steel.

Methods to identify stainless steel are simple
Distinguishing real stainless steel based on its shine
Distinguishing real and fake stainless steel can be easily done through its shine and smoothness. Real stainless steel will have a shiny and smoother surface than fake stainless steel. Fake stainless steel often has a duller shine and is less smooth. Over time, fake stainless steel often cannot maintain its original brightness and may begin to fade. In addition, some products may have small cracks and stains on the surface.

Distinguish real stainless steel using a magnet to check
This method of distinguishing real stainless steel is most often applied. You can put a magnet near a stainless steel product to test its magnetic properties. If the magnet has heavy attraction and pulling force, it is a sign of magnetism appearing, which means it is not real stainless steel. On the contrary, if the suction and pulling force are light, it is real stainless steel. However, it should be noted that the specific stainless steel composition of the product may affect the magnetic properties. Different types of stainless steel have different magnetic characteristics:
– SUS430: magnetic, easily affected by the environment and likely to tarnish.
– SUS202: magnetic, easily affected by the environment and likely to tarnish.
– SUS201: non-magnetic (99%), durable over time, but direct contact with acids or salts should be avoided.
– SUS304: non-magnetic, suitable for all environments, maintains shine and ensures food safety.
– SUS316: non-magnetic, can be used in all environments, including environments requiring high cleanliness.

Use 70 degree hot acid or specialized testing solution
To check the quality of fake stainless steel surfaces, using 70 degree acid will change the color to black. Meanwhile, real stainless steel will retain its original color. However, for more delicate products, coated with a thin layer of 304 stainless steel, using 70-degree acid seems ineffective, but after a period of use, this thin layer of stainless steel can peel off and cause damage. Corrosion to the metal inside.
Check chemical composition at the testing center
To ensure accurate distinction between real stainless steel, stainless steel can be brought to a testing center to determine the chemical composition of the material. This method not only helps distinguish between real and fake stainless steel but also determines the type/grade of stainless steel. The basic components in stainless steel are as follows:
– Stainless steel 201: 0.8% – 4.5% Nickel and 7.1% Manganese
– Stainless steel 304: 8.1% Nickel and 1% Manganese
– Stainless steel 430: 0% Nickel and 18% Chromium
However, this is a time-consuming and expensive testing method because the center needs to take specific steps and needs time to provide official documents for the testing process.
How to distinguish specific stainless steel products
Stainless steel pots, a stainless steel product commonly used in home and industrial kitchen equipment, are often easily counterfeited. To distinguish between real and fake stainless steel, in addition to the previous methods (brightness, magnetism, 70 degree acid, chemical test), we can also pay attention to the resonance of the pot. By tapping on the bottom of the pot and listening, if the resonance is high, it is likely that it is not quality stainless steel but stainless steel mixed with many impurities or only has a thin layer of chrome plating.
