The difference between chromium vanadium steel and chromium molybdenum steel is that the composition is different, the former contains vanadium (V) and the latter contains molybdenum (Mo).
Chromium vanadium steel is mainly used for products with high wear resistance and toughness requirements, and chromium molybdenum steel is mainly used for products with high performance requirements and easy to forge.
The hardness of the two materials is similar. Generally, tool steel, chrome vanadium steel, and high carbon steel are commonly used for pliers. Chrome molybdenum steel is generally used for screwdrivers.
Compared with carbon steel, alloy steel welding rod contains more other elements.
Alloy steel refers to steel containing silicon and manganese as alloying elements or deoxidizing elements, but also other alloying elements (such as chromium, nickel, molybdenum, vanadium, titanium, copper, tungsten, aluminum, cobalt, niobium, zirconium and other elements) Etc.), some also contain some 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.
The carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally do not add a large amount of alloying elements, sometimes also called normal carbon steel or carbon steel.
Carbon steel is also called carbon steel, an iron-carbon alloy with a carbon content of less than 2% WC. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus. Carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel according to its purpose. Carbon structural steel is divided into two types: architectural structural steel and machine-manufactured structural steel. According to carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC>0.6%) according to phosphorus and sulfur content Carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur) and high-grade high-quality steel (lower phosphorus and sulfur). General carbon steel contains carbon. The higher the amount, the higher the hardness and the higher the strength, but the lower the plasticity.
