Alloy Round Steel Bar

1. Alias: Alloy Steel Pipe
2. Composition: In addition to iron and carbon, other alloying elements are added
3. Performance: wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, etc.
4. Grades: Element types contained in general naming principles Metal elements and non-metal elements
5. In addition to iron and carbon, alloy steel is called alloy steel by adding other alloying elements. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the difference of added elements and appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties can be obtained.
6. The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc.
   Among them, vanadium, titanium, niobium, zirconium, etc. are strong carbide forming elements in steel. As long as there is enough carbon, under appropriate conditions, their respective carbides can be formed. When carbon is lacking or under high temperature conditions, atomic The state enters the solid solution; manganese, chromium, tungsten, and molybdenum are carbide forming elements, some of which enter the solid solution in an atomic state, and the other part forms a substitutional alloy cementite; aluminum, copper, nickel, cobalt, silicon, etc. are not formed. Carbide elements generally exist in solid solution in an atomic state.
7. There are many types of alloy steel, usually divided into low alloy steel (content <5%), medium alloy steel (content 5% ~ 10%), high alloy steel (content> 10%) according to the content of alloying elements; according to quality, it is divided into high-quality steel Alloy steel, special alloy steel; according to characteristics and uses, it is divided into alloy structural steel, stainless steel, acid-resistant steel, wear-resistant steel, heat-resistant steel, alloy tool steel, rolling bearing steel, alloy spring steel and special performance steel (such as soft magnetic steel). , permanent magnet steel, non-magnetic steel) and so on.
8. The alloy steel systems of various countries vary according to their respective resource conditions, production and use conditions. In the past, nickel and sintered steel systems have been developed in foreign countries. In my country, silicon, manganese, vanadium, titanium, niobium, boron, lead and rare earth are found as The main alloy steel system Alloy steel accounts for about ten percent of the total output of steel. Generally, alloy steel is smelted in electric furnaces and can be divided into 8 categories according to use. They are: alloy structural steel, spring steel, Bearing steel, alloy tool steel, high-speed tool steel, stainless steel, heat-resistant non-skinned steel, silicon steel for electrical use.songshunmoldsteel41404340
