What is Alloy Steel?
Alloy steel In addition to iron and carbon, alloy steel is called alloy steel. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to an ordinary carbon steel. According to the different added elements, and adopt appropriate processing technology, high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties can be obtained.
- Effect of alloying elements on phase diagram of iron-carbon alloy
- 1.According to the content of alloying elements
- 1) The total content of alloying elements in low alloy steel is 5% or less;
- 2) The total content of alloying elements in medium alloy steel is between 5% and 10%;
- 3) The total content of alloying elements in high alloy steel is 10% or more;
- 2, according to the type of alloy element
- There are chrome steel,
- General naming principles of alloy gold grades
- The carbon content of alloy steel, the types of alloy elements, and the content of alloy elements should be reflected in the grade.
- Example: Alloy spring steel 60Si2Mn
- Carbon content ~ 0.6%; silicon content ~ 2%; manganese content Mn ~ 1%.
- Alloy steel electrode
- Alloy steel refers to steel in addition to silicon and manganese as alloying elements or deoxidizing elements, but also contains other alloying elements, and some also contain certain non-metallic elements of steel. According to the content of alloy elements in steel, it can be divided into low alloy steel, medium alloy steel and high alloy steel.
- Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content of the steel, and generally does not add a large amount of alloying elements, sometimes called ordinary carbon steel or carbon steel.
- Carbon steel is also called carbon steel, iron-carbon alloy with carbon content WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus. According to use, carbon steel can be divided into carbon structural steel, carbon tool steel, and free-cutting structural steel. According to the carbon content, carbon steel can be divided into low carbon steel (WC 0.25%), medium carbon steel (WC 0.25%-0.6%) and high carbon steel (WC> 0.6%) [11]
- Generally, the higher the carbon content in carbon steel, the higher the hardness and the higher the strength, but the lower the plasticity.
