Here we introduce 3 ways to judge stainless steel bracelets:

1. First of all, it must be different in color. The surface of the stainless steel bracelet that has been pickled is white and bright: chrome-nickel stainless steel is snow-white and jade-like; chrome stainless steel is white and slightly gray and has weak luster; The appearance color of the stainless steel bracelet without pickling: chromium nickel steel is brownish white; chrome steel is brownish black; chromium manganese nitrogen is black.
2. It is to remove the oxide layer on the surface of the bracelet, put a drop of water and wipe the surface of the bracelet with copper sulfate, the one that does not change color is usually stainless steel; if it turns purple: the non-magnetic one is high manganese steel, and the magnetic one is usually ordinary steel or low alloy steel.
3. It is judged by a magnet, which can basically distinguish the two types of stainless steel bracelets. Because chromium stainless steel can be attracted by magnets in any state; chromium-nickel stainless steel is usually non-magnetic in the annealed state, and some will be magnetic after cold working, but high manganese steel with higher manganese content is non-magnetic ; The magnetic state of chromium-nickel-nitrogen stainless steel is more complicated: some are non-magnetic, some are magnetic, and some are non-magnetic in the longitudinal direction and magnetic in the transverse direction.
