How to distinguish stainless steel bracelets from bracelets made of other materials
There are many styles of bracelets sold on the market, and the quotations are also uneven. Because stainless steel bracelets are more expensive than bracelets made of other materials, there are countless bracelets of various materials that fake stainless steel bracelets on the market. Usually, it is difficult to distinguish with the naked eye. from. The following jewelry companies introduce us to 3 methods for determining stainless steel bracelets:
The main difference is in color. The stainless steel bracelet that has been pickled has a white and bright appearance: chrome-nickel stainless steel is snow-white and jade-colored; chrome stainless steel is white and slightly gray and weak; chrome-manganese-nitrogen stainless steel is similar to chrome-nickel stainless steel. Appearance color of acid-washed stainless steel bracelet: chrome-nickel steel is brown-white; chrome-steel is brown-black; chrome-manganese nitrogen is black
The second method 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 non-discolored is usually stainless steel; if it turns purple: non-magnetic high-manganese steel, magnetic is usually Usually steel or low alloy steel.
The third method is to use magnets to determine the difference between two types of stainless steel bracelets. Since chromium stainless steel can be attracted by magnets in any state; chromium-nickel stainless steel is usually non-magnetic in the annealed state. After cold working, some will be magnetic, but high manganese steel with high 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 vertical and magnetic in transverse.
