Everyone knows that stone mountain carving have many advantages, so many urban stone mountain carving use stone carving materials as materials to make stone mountain carving. So how much do you know about the material content of stone mountain carving. Below, the stone mountain carving manufacturer will talk about the material content of stone mountain carving.
Let`s first understand what stone sculpture is, but in an academic sense, it is steel that is resistant to corrosion by weak corrosive media such as air, steam, and water, and chemically corrosive media such as acids, alkali, and salts. Also known as stainless acid-resistant steel. In practical applications, steel that is resistant to corrosion by weakly corrosive media is often called stone sculpture, while steel that is resistant to corrosion by chemical media is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not resistant to corrosion by chemical media, while the latter is generally stainless. The corrosion resistance of stone sculptures depends on the alloying elements contained in the steel. Chromium is the basic element that makes stone sculptures corrosion resistant. When the chromium content in steel reaches about 12%, chromium interacts with the oxygen in the corrosive medium to form a thin oxide film (self-passivation film) on the surface of the steel. , which can prevent further corrosion of the steel matrix. In addition to chromium, commonly used alloy elements include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc. to meet the requirements for the structure and performance of stone sculptures for various purposes.
