Carton packing foam protectionA vessel, especially one that is used to hold an object, is called a basin because it is larger in shape than a bowl.
The essential difference between basin and bowl lies in that the edge of basin is thicker than the inner wall, and the edge of bowl is thinner than the inner wall the only problem is that stainless steel without ferromagnetism contains nickel and chromium, and ferromagnetic stainless steel replaces very expensive nickel with lots of manganese (since manganese and chromium alloys have the opposite effect, and more manganese must reduce nickel) and reduce the content of the corrosion resistant element chromium. Therefore, the corrosion resistance is poor. Let me explain in detail.
The so-called stainless steel basin is not magnetic, in fact, can not be attracted by magnets, should be called non-ferromagnetic.
Stainless steel which cannot be attracted by magnets is mainly composed of austenite structure and is generally 304 stainless steel used by food industry and medical industry.
And the stainless steel that can be attracted by magnet contains a lot of ferrite inside, it is to decorate commonly the 201, 430 stainless steel that use and low corrosion-resistant performance. |
