All the time, many customers have the question that why the 304 stainless steel hinge can be absorbed by the magnet in the use of them. Just let us have a brief analysis.

The regular hinge manufacturers choose 304 and 201 stainless steel hydraulic hinge as the raw material that made the hinge, while some of them may use the inferior material to pretend the 304 stainless steel in order to earn profit. Customers cannot distinguish the stainless steel hinge with eyes, so they usually use the magnet to judge whether it is the stainless steel hinge

In fact, we use the magnet to absorb the stainless steel directly to judge the material is not correct. A shaped hinge is made of many components which is punched by the mold, the raw material is stainless steel, while the punching mold is iron, it will produce the mechanical magnetic 2, and the fittings within the hinge is stainless iron, the hinge can be absorbed through the 304. So it is normal to be attracted when use the magnet to attract them directly. If they have performed the magnet treatment, then they can’t be absorbed, generally few manufacturers have done this.

Only by using the medical water can test whether it is the pure 304 material.Here is the link: http://url.alibaba.com/r/aHR0cDovL3Yua3U2LmNvbS9zaG93L2Vlc2lmNGIzdHlfcmNjb2EuaHRtbD9sb2M9dGFzaGFuZ2NodWFu (Note: It is the medical water that specialized in testing the stainless steel where you can find in the hardware store). Drop the medical water into the hinge, if the color changed, it proves to be the 304 stainless steel, if it turns out to red, it might be made by 201 or other material.

In fact, customers can choose the material of hinge according to their own usage, like the 304 stainless steel hydraulic hinge , has a strong rust resistance, often used in the bathroom cabinet, while the 201 stainless steel hydraulic hinge has a weak rust resistance, so the price of 304 is higher than other materials.www.kavslide.com
