Alloy steel can be used as the raw material of alloy steel pipe fittings, alloy steel tubes and alloy steel plates.According to the different chemical elements can be divided into different alloy steel grades .
In order to improve and improve the performance of steel, in the carbon steel on the basis of other Alloy elements, such as silicon, manganese, chromium, nickel, tungsten, vanadium, titanium and so on, this steel is called Alloy steel.According to the different alloy elements, alloy steel has different properties, such as high abrasion resistance, corrosion resistance, low temperature resistance, high magnetic and other good special properties.Alloy steels are classified into alloy structural steels, alloy tool steels and special properties steels according to their USES.
Alloy steel vs carbon steel
Alloy steel vs stainless steel
Ordinary low-alloy steel has the following advantages over similar carbon steel:
1: high strength, good plasticity and toughness.Due to the action of alloying elements, its strength is 25%--50% higher than that of ordinary carbon steel, its elongation is 15%--23%, and its impact toughness is higher than 60J/cm^2 at room temperature.
2: good weldability.Due to the low carbon content, alloy element content, its good plasticity, hardenability is low, should not appear in the weld quenching structure or cracks.
3: hot and cold pressure processing performance is good.Due to its good plasticity, deformation resistance is small, the pressure processing is not easy to produce cracks.
4: good corrosion resistance.It has higher corrosion resistance than carbon steel under various atmospheric conditions.
Characteristics of alloy steel
Pure metal has good toughness, high thermal conductivity and electrical conductivity, but the application of pure metal is very limited.Because in the pure metal can not find the hardness, elasticity, strength and other aspects of the metal material is very high, and different kinds of alloy steel can meet various requirements.The reason why alloy has better and more physical and mechanical properties than pure metal, has been widely used in the national economy and people's livelihood, is because it has more types of internal structure, and can be manually controlled this advantage inseparable.
