Identified by magnetite, magnets can fundamentally differ between two types of stainless steel grills. Since chromium stainless steel can be attracted by magnets in any state, chromium nickel stainless steel is generally non-magnetic in the annealed state, and some stainless steel grills will be magnetic after cold working. But the high manganese steel with higher manganese content is non-magnetic.
The magnetic condition of chromium-nickel-nitrogen stainless steel is more messy. Some are non-magnetic, some are magnetic, and some stainless steel grills are non-magnetic in the longitudinal direction and magnetic in the horizontal direction. Therefore, although magnets can fundamentally distinguish between chrome stainless steel grills and chromium nickel stainless steels, they cannot correctly distinguish some special types of steel, let alone distinguish detailed steel numbers.
The identification of the potion in stainless steel is mainly to facilitate customers to identify various raw materials for stainless steel barbecue nets. Its biggest advantage is to distinguish the content of the first chemical composition of stainless steel. Drop the stainless steel medicine on the stainless steel barbecue net, you can distinguish the raw materials of stainless steel in 1~2 minutes: 10s to red is 201 raw materials, 20s to red is 202, 30s to red is 301, and the unchanged red is 304 raw materials.https://www.evergrillw.com/
