It turns out that stainless steel will also fall in love with magnets

In life, everyone will have such a perception: iron can be attracted by magnets, and stainless steel cannot be attracted by magnets. This is a false perception to judge whether the stainless steel products purchased are fake. It is said that "100-made steel" stainless steel is also born out of iron, only because of the difference in carbon content will it show different magnetic properties. The types of stainless steel can be divided into: ferritic stainless steel, austenitic stainless steel, martensitic stainless steel. Among them, austenitic stainless steel is non-magnetic or weakly magnetic and cannot be attracted by magnets, while martensitic and ferritic stainless steels are magnetic and can be attracted by magnets.


The pros and cons of a stainless steel product cannot be judged based on whether stainless steel can be attracted by a magnet. Some low-quality stainless steel products will be doped with a large amount of manganese, and manganese metal cannot be attracted by magnets, but the corrosion and rust resistance of stainless steel products doped with manganese will be much reduced.


On the contrary, like martensitic stainless steel products, although they have magnetism, they have super high strength and corrosion resistance. Therefore, just relying on magnets to judge the quality of stainless steel products is definitely out of context. Hebang’s main SUS410 fastener products are made of martensitic stainless steel. Coupled with our special heat treatment process, our products truly have the quality comparable to imported products.
