Is completely on the human body will not produce any side effects and no harm to green high-end environmental protection ornaments. The corrosion resistance of stainless steel ornaments depends on the alloying elements contained in the steel. Chromium is to make stainless steel to obtain the basic elements of corrosion resistance, when the chromium content of steel reached about 12%, chromium and corrosive medium oxygen, in the steel surface formation of a very thin oxide film (self-passivation film), can prevent the steel matrix further corrosion. In addition to chromium, the commonly used alloy elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. to meet the various uses of stainless steel structure and performance requirements. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and the corrosion resistance of chloride is superior to other kinds of stainless steel.
