In the jewelry market, stainless steel necklace has won the favor of consumers with its unique charm and diverse designs. Among them, its excellent corrosion resistance has won it the reputation of "king of durability".
Stainless steel is a kind of alloy steel with corrosion resistance, usually composed of iron, carbon, chromium and other elements. Among them, chromium is the basic element for stainless steel to obtain corrosion resistance. When the chromium content in steel reaches about 12%, chromium reacts with oxygen in the corrosive medium to form a very thin oxide film (self-passivation film) on the surface of the steel, which can effectively prevent the steel matrix from being further corroded. In addition, alloy elements such as nickel, molybdenum, and titanium may be added to stainless steel to improve its corrosion resistance, toughness and weldability.
The corrosion resistance of stainless steel necklace is based on this special alloy composition and surface treatment technology. In daily life, we often come into contact with various acidic and alkaline substances, such as sweat, cosmetics, detergents, etc. These substances may corrode the jewelry, causing discoloration, rust or damage to the surface. However, stainless steel necklace can maintain its beauty and luster for a long time in these harsh environments with its excellent corrosion resistance.
Specifically, the corrosion resistance of stainless steel necklace is manifested in the following aspects:
Acid and alkali resistance: stainless steel necklace has strong resistance to acid and alkali substances. Even when it comes into contact with acid and alkali substances such as sweat and cosmetics, it can keep the surface from corrosion, thereby extending its service life.
Antioxidation: The surface of stainless steel necklace is not easily oxidized, and even in a humid or high temperature environment, it can maintain its color for a long time and is not easy to fade.
Wear resistance: In addition to corrosion resistance, stainless steel necklace also has high hardness and wear resistance, is not easily subject to wear and deformation, and further extends the service life of the jewelry.
Easy to clean: Since the surface of stainless steel necklace is smooth and not easy to be contaminated, it is very convenient to clean. Just wipe it gently with a soft cloth to restore its original luster.
However, it is worth noting that despite the excellent corrosion resistance of stainless steel necklace, it still needs to be maintained in some special cases. For example, when in contact with strong acid, strong alkali or high temperature environment, you still need to wear it with caution to avoid unnecessary damage to the jewelry. In addition, for people with sensitive skin, a small area of skin test is also required when choosing a stainless steel necklace to ensure that it will not cause allergic reactions.
In general, the corrosion resistance of stainless steel necklace is one of the important reasons why it is so popular. It can not only maintain long-term beauty and luster in various harsh environments, but also has the advantages of wear resistance and easy cleaning.
