Stainless Steel Kitchen Sink  water is a sink product with stainless steel as the primary material. It is generally believed that stainless steel is a non-toxic material and one of the world's recognized metal materials that can be implanted into the human body.

At present, the sinks on the market are mostly made of copper, accounting for up to 95%, while the stainless steel cabinets account for only about 5%. However, with the increasingly sophisticated production process of domestic manufacturers, combined with the original health, environmental protection, and use characteristics of stainless steel kitchen sinks, it has been favored by more and more consumers in recent years.

Take the mainstream 304 stainless steel kitchen sink as an example. Its anti-rust principle is that the alloy elements form a fine oxide film, which blocks the oxygen touch and prevents continuous oxidation. In practical applications, steels resistant to weakly corrosive media are generally referred to as stainless steel, while steels resistant to chemical media are referred to as acid-resistant steels. Stainless steel is not necessarily resistant to chemical media corrosion, but acid-resistant steels generally have rust properties.

The corrosion resistance of stainless steel depends on the alloying elements contained in the stainless steel. Chromium is the fundamental element that makes stainless steel corrosion-resistant. When the chromium content in steel reaches about 1.2%, chromium reacts with oxygen in the corrosive medium to form a thin oxide film on the steel surface called passivation film. The substrate used to organize the steel is further corroded. In addition to chromium, commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to satisfy the requirements of stainless steel structure and performance for various purposes.
