How to identify whether stainless steel mesh contains nickel or not...

The stainless steel mesh is widely used in petroleum, chemical industry, environment protection, mine, airspace, electronic, etc due to its anti-rust, anti-acid and salts, high-temperature resistance, and abrasion resistance.
Today MAISHI wants to share some methods to identify whether is it real stainless steel and whether is containers Nickel or not.
 
The most commonly used method: the magnet test.
High-quality steel itself does not contain iron, so, the magnetization effect is not strong. Chromium alloy has an anti-magnetic effect, the steel is not easy to magnetize after adding the chromium. As long as using a common magnet can test if it is stainless steel.
 
It is hard to distinguish stainless steel wire mesh with naked eyes, so the better method is to test by the syrup:
 
Drop 1-2 drops of stainless steel test solution on the material which is to be tested, wait a few seconds, then it will show the effect.
Droplets instantly become dark red if there is no nickel in the material;
201 stainless steel, droplets instantly become dark brown;
202 stainless steel, droplets in about 5 seconds into a light brown red;
301 stainless steel, droplets become a light brick in 1-2 minutes;
304 stainless steel, droplets do not change within 3-5 minutes.
 
But sometimes, the above two methods can’t correctly test the real material, So, MAIWHI bought the Handheld XRF Analyzers (X-Ray Fluorescence), which can Inspect Alloy materials and nickel correctly and the tolerance of less than 5%. In this way, we guarantee our quality.
