The material of the stainless steel shower faucet is based on stainless steel, so let's first look at the characteristics of stainless steel. Stainless steel refers to metal materials that have certain chemical stability in the atmosphere, water, acid, alkali, salt and other solutions, or other corrosive media. When the composition of stainless steel contains a certain proportion of chromium and nickel, its corrosion resistance will undergo a sudden change, that is, it will become corrosion resistant and not easy to rust. The 304 stainless steel material contains more than 18% chromium, and about 8% nickel, molybdenum, titanium, silicon, aluminum and other trace elements.
These elements have high chemical stability and will form an oxidized passivation film on the surface of the steel. This film is extremely thin and transparent, and can only be seen under a microscope. What you can see with the naked eye is a shiny silver metal surface. This passivation film isolates the stainless steel from external media such as air, acidic liquids, etc., protects it from oxidation, and enhances its corrosion resistance. Once the passivation film is damaged, the chromium and nickel in it will regenerate the passivation film with oxygen ions and continue to play a protective role. Because of this self-repairing function, 304 stainless steel has high corrosion resistance and will never rust.
There are many grades of stainless steel. Common stainless steel models include 316#, 304#, 202#, 201#, etc., of which 201# is stainless steel, 304# is stainless steel that meets the standards of food products, and 316# has strong anti-corrosion ability for marine and medical use. Stainless steel. 304 stainless steel has bright surface, high plasticity, good toughness, high mechanical strength, and has the characteristics of welding and bending deformation. It is corrosion resistant and does not rust in acid and alkali gases, solutions and other media. The easy way to check the authenticity of 304 stainless steel is: first, soak in concentrated brine for 200 hours to see if there is any change; second, soak in concentrated acid for 10 hours to see if there is any change.
The stainless steel shower faucet is healthy and environmentally friendly without lead. Stainless steel does not contain lead, is acid and alkali resistant, does not corrode, does not release harmful substances, and will not pollute your tap water source. It is beneficial to human health, hygiene and environmental protection. The surface of the stainless steel faucet is never rusty, beautiful and durable, and easy to clean. The surface of the stainless steel faucet does not need to be electroplated, and its surface only needs to be polished (polished) to show the true color of the stainless steel, and it will always maintain the silver-white luster and never rust.
According to statistics, the polished surface of stainless steel products is still clean and beautiful and luxurious as new after 10, 20, and 30 years of use. At present, kitchen utensils and tableware made of stainless steel are popular all over the world. We have hardly seen copper tableware and kitchen utensils. The hardness and toughness of stainless steel are more than 2 times higher than that of copper. Never rust, never corrode, never deform. The surface of copper products must be electroplated, and the best treatment method for the copper surface is to electroplate a layer of nickel or chromium. The electroplating layer will gradually peel off depending on its electroplating quality and thickness.
