Stainless steel jewelry is a very special metal accessories, texture is very tough, but very resistant to corrosion, it does not like the silver will turn black, copper and the like do not like jewelry easy to allergies, but not as alloy jewelry because lead and toxic, and stainless steel jewelry has always been at room temperature for life to maintain their color. Stainless steel jewelry the same material from the inside to the outside, and through artificial sweat test, its characteristics, completely non-corrosive, and resistant to acid, alkali resistant, not color, not fading, not allergic, no deformation, hard, bright. It is entirely on the human body does not produce any side effects and no harm to the green high-grade green jewelry. The corrosion resistance of stainless steel jewelry, steel depends on the alloying elements contained. Chromium is to corrosion resistance of stainless steel to obtain the basic elements, when the chromium content in steel reaches containing about 12% chromium and corrosive media, the role of oxygen in the steel surface of a thin oxide film (from the passive film) , can prevent further corrosion of the steel substrate. In addition to chromium, the commonly used alloying elements nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the various uses of stainless steel organization and performance requirements. Its corrosion resistance, toughness and weldability with the increase of chromium content increased resistance to chloride stress corrosion better than other types of stainless steel.
