How to test the authenticity of stainless steel hydraulic hinge_Hinge Knowledge 1

Stainless steel hydraulic hinges are primarily used as cabinet door hinges in both cabinets and bathrooms. Customers opt for these hinges primarily because of their anti-rust functionality. However, the market offers various hinge materials, including cold-rolled steel plates, stainless steel 201, and stainless steel 304. While identifying cold-rolled steel plate materials is relatively easy, distinguishing between stainless steel 201 and 304 can be more challenging. Both materials are made from stainless steel and have similar polishing treatments and structures.

There is a price difference between stainless steel 201 and 304 due to variations in their raw materials. This price gap often leaves customers concerned about accidentally purchasing 201 or iron products at the higher price of 304. Currently, the market offers stainless steel hydraulic hinges with prices ranging from a few cents to several dollars. Some customers even contact me to inquire about hinges made specifically from 304 stainless steel. This situation leaves me speechless! Just imagine the market price for a ton of stainless steel materials and the cost of a hydraulic cylinder. Putting aside the cost of raw materials, a hinge costs more than a few cents when considering factors such as manual assembly and stamping machine parts.

One common misconception is that a smooth and shiny polished surface indicates the presence of a stainless steel hinge. In reality, hinges made from authentic stainless steel materials will have a dull and lackluster appearance. Some customers resort to using special stainless steel solutions to test hinges in order to confirm their stainless steel composition. Unfortunately, this potion test only has a 50% success rate for polished stainless steel products because these products have a layer of anti-rust film attached to them. Thus, the success rate of directly using the potion test is not high, unless the anti-rust film is scraped off before conducting the test.

There is another more direct method to determine the quality of the raw materials, provided individuals have the necessary tools and are willing to put in some effort. By using a grinding machine to grind the raw materials, one can judge their quality based on the sparks produced during the process. Here's how to interpret the sparks:

1. If the polished sparks are intermittent and scattered, this indicates iron material.

2. If the polished sparks are relatively concentrated, thin, and elongated like a line, with thin spark points, this suggests material above 201.

3. If the polished spark points are concentrated on a single line, with a short and thin spark line, this suggests material above 304.
