How to distinguish the authenticity of stainless steel water tank materials?
At present, the main stainless steels sold in the Chinese market are the 300 series and 200 series. The difference between the two lies in the amount of chemical element nickel content, which causes a huge difference in their performance and price. At the current nickel price level, the price of 200 series stainless steel with very low nickel content is only about half of that of 300 series stainless steel, and its anti-corrosion and toughness performance is far inferior to 300 series stainless steel. It is only suitable for fields such as kitchen utensils and food processing. If used in fields such as construction and medical equipment, there will be great hidden dangers. The 200 series products with a nickel content of about 1% cannot withstand general atmospheric corrosion.

It is difficult to distinguish the difference between the 200 series stainless steel and the 300 series stainless steel on the surface, even experts cannot distinguish it. In order to prevent users from suffering losses, we are here to teach you how to identify the material of stainless steel water tanks.
The method is as follows:
1. Touch with a magnet to see if it is magnetized. Unless otherwise specified, it is generally non magnetic. If magnetic, it may be replaced by low-grade ferrite materials (such as 430).
It is also unscientific and incorrect to judge the quality of stainless steel solely based on the presence or absence of magnetism. Our concept has led to low nickel, low chromium, but non magnetic stainless steel in the market being inferior and deceiving users. Stainless steel water tank products may experience rusting, fracture, and swelling after short use. Due to the fact that there is no difference on the surface between the 200 series stainless steel and the 300 series stainless steel, and both have no magnetism, the only way to identify their quality is to conduct chemical composition analysis at a local mechanical research institute or a unit with metal testing capabilities.
When purchasing a stainless steel water tank, it is important to have the manufacturer indicate the product material and issue a material certificate and warranty. To prevent economic losses and potential risks to the project, please choose a reputable stainless steel water tank manufacturer!
