The difference between alloy ring and carbon steel

1. Definition of steel: Steel can be divided into carbon steel and alloy steel according to its carbon content and alloy content. Steel also generally refers to iron-carbon alloys, or a solid solution of carbon in crystalline iron. Steel means that in addition to silicon and manganese as alloying elements or deoxidizing elements, steel also contains other alloying elements (such as chromium, nickel, molybdenum, vanadium, titanium, copper, tungsten, aluminum, cobalt, niobium, zirconium and other elements, etc.) , and some also contain certain non-metallic elements (such as boron, nitrogen, etc.) steel. According to the content of alloying elements in steel, it can be divided into low alloy steel, medium alloy steel and high alloy steel. Steel refers to the steel that contains a certain amount of alloying elements such as silicon (generally not more than 0.40%) and manganese (generally not more than 0.80%, higher content can reach 1.20%) for deoxidation, and does not contain other alloying elements ( excluding residual elements). According to the unevenness of the content, it can be divided into low carbon steel (carbon content is generally less than 0.25%); medium carbon steel (carbon content is generally between 0.25%-0.60%); greater than 0.60%). But there is no harsh border between them.

2. Definition of alloy ring: Steel containing other alloying elements is alloy ring. The total content of alloying elements can reach 10~28%, which is high alloy steel. Alloy ring, in addition to iron and natural elements in steel, also added other alloying elements to change or improve some characteristics of steel, such as CrNiMnMoWVB and so on. In addition to iron and carbon, some other metals are intervened in the alloy ring to change the function of the material. The role of chromium is to make the steel resistant to corrosion, and the role of nickel is to reduce the austenitization temperature of stainless steel.

3. Definition of carbon steel: Carbon steel does not contain other alloying elements; carbon steel is also steel with a carbon content of less than 1.35%. Carbon steel, that is, in addition to iron, there are generally only five natural elements such as carbon, silicon, manganese, phosphorus and sulfur, and no other alloying elements are added.

Fourth, the difference between alloy ring and carbon steel: Carbon steel does not contain useful alloying elements, and is an alloy with iron, carbon and manganese as the main elements. The mechanical performance is usually not as good as the alloy ring. Moreover, the price of carbon steel is much lower than that of alloy seamless steel pipe. From the above two points, the supplier of gold steel rings believes that the performance of alloy rings exceeds that of carbon steel is the biggest difference.
