We can do PVD(Physical Vapor Deposition) plating to make these colors. Normally the thickness of the plating layer is about 0.05mm. But we can make as customers’ demand. We ensure the plating color won’t fade for 1~3 years.

How to identify stainless steel jewelry? There are four main identification methods to share:

1. Magnet detection method

The chemical composition of stainless steel is complex, and the processing technology is different. It is inaccurate and unrealistic to use a simple method to detect.

Stainless steel can change the magnetic characteristics of stainless steel through demagnetization or magnetization process, and it is inaccurate to test with a magnet alone. Usually cheap stainless steel can be demagnetized to pretend to be high-quality stainless steel; at the same time, high-quality stainless steel sometimes needs to be magnetic to increase operability.

2. copper sulfate identification method

The method is to remove the oxide layer on the steel, put a drop of water, and wipe it with copper sulfate. or low alloy steel.

3. Reagent detection method

This is a fast detection method, which uses several detection reagents to detect the content range of nickel, chromium and molybdenum in stainless steel.

The advantages are: convenient, fast and basically accurate.

The disadvantage is: there is a deviation in the operation, and the test results can only be used for rough judgment, not as a precise conclusion.

4. Accurate judgment

If it is necessary to make accurate model judgment on stainless steel samples, it is necessary to send the samples to a testing institution with corresponding qualifications for testing, in order to obtain an authoritative conclusion.

Laboratory testing institutions conduct testing

We can do the test to identify the stainless steel, even distinct the 304 and 316 material in our laboratory lab. Send us your sample, we can identify that’s 304 or 316 material. There’s also the third-party issue the report.
