Good design stainless steel jewelry is elegant and luxury, used on occasions such as Anniversary, Engagement, Gift, Party, Wedding…

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.

Process flow of stainless steel jewelry casting

图片
Process flow of stainless steel jewelry casting : Stainless steel jewelry casting process is usually to produce irregular shaped jewelry, including rings, pendants, bracelets and other special-shaped pieces. 1. Because stainless steel casting cools and solidifies faster in the metal mold than in the sand mold, and the metal mold has no tolerance, so when the metal mold is cast, the casting stress generated in the casting is larger than that of the sand casting, and the crack tendency is also large. It is easy to produce defects such as insufficient pouring, cold insulation, and white mouth (for castings). usually: (1) The following structural problems should be paid attention to in preventing insufficient pouring and cold isolation in stainless steel casting: A. The shape of the casting should be as streamlined as possible to avoid sharp edges and sharply changing connections, so as to facilitate the flow of molten metal ;B. The wall thickness of the casting should be appropriate and ...

Stainless Steel Jewelry VS Gold?

Stainless Steel Jewelry VS Gold? : Difference: Stainless steel jewelry is more fashionable than gold jewelry, and stainless steel is less expensive than gold jewelry. Gold, wearing gold and silver has been very popular since ancient times, and it is also very high-end. Of course, it is very high-end, so its price is also very high-end. Gold is the most suitable for the human body, and it is also considered a rare element. So gold is my favorite jewelry. And it still retains its value, but if I buy it, I won't take it with me. I am afraid that others are friends with me because of my money (just kidding). The advantages need not be said more, the disadvantages and the styles are few. The style is not novel enough. Gold material Stainless steel, the advantage is that the price is cheap, the color retention is good, there are many styles, and it is hypoallergenic. The jewelry is probably about 0.1 to 10 US dollars. Don't ask me why I know it, because I am the manufacturer. Stainl...
