Identification with magnetite
Magnet can basically distinguish two types of stainless steel grills. Because chromium stainless steel can be attracted by magnets in any state, chromium nickel stainless steel is generally non-magnetic in the annealed state. After cold working, some stainless steel grills will be magnetic. But the high-manganese steel with higher manganese content is non-magnetic; the magnetic situation of chromium-nickel-nitrogen stainless steel is more complicated. Some are non-magnetic, some are magnetic, and some stainless steel barbecues are non-magnetic in the longitudinal direction and magnetic in the horizontal direction. Therefore, although magnets can basically distinguish between chrome stainless steel grills and chrome-nickel stainless steel, they cannot correctly distinguish some special types of steel, nor can they distinguish specific steel numbers.
Second, the stainless steel identification potion is mainly for the convenience of customers to identify various stainless steel barbecue mesh materials. Its biggest advantage is to analyze the content of the main chemical components of stainless steel. Drop the stainless steel medicine on the stainless steel barbecue net, and the material of the stainless steel can be distinguished in 1~2 minutes: 10s red to 201, 20s red to 202, 30s red to 301, and constant red to 304.https://www.evergrillw.com/
