What is Alloy steel
- Sep 17, 2018 -

1. Alloy steel In addition to iron, carbon, adding other alloying elements, called alloy steel. 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 different elements, and take the appropriate processing technology, can obtain high strength, high toughness, wear resistance, corrosion resistance, low temperature, high temperature, non-magnetic and other special properties.


2. The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth and so on. wherein vanadium, titanium, niobium, zirconium and so on in the steel is the strong carbide-forming elements, as long as there is enough carbon, under appropriate conditions, can form their own carbide, when the carbon deficiency or under high temperature conditions, the atomic state into a solid solution; manganese, chromium, tungsten, molybdenum are formed elements of carbide, which part of the atomic state into the solution,

The other part forms the replacement alloy cementite, aluminum, copper, nickel, cobalt, silicon and so on are not formed carbide elements, generally in the atomic state exists in the solid solution.


 Alloy steel is an important material used in our daily production, its good physical and chemical properties determine its wide application in welding, forging, stamping and so on.
