1.What is Alloy Steel Casting?

Low alloy steel refers to alloy steel with a total alloying element content of less than 5%. Low alloy steel is relative to carbon steel. On the basis of carbon steel, one or more alloying elements are intentionally added to the steel in order to improve the performance of the steel. The amount of alloy added exceeds the average content of alloying elements contained in carbon steel during normal production. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to ordinary carbon steel. Depending on the added elements and the 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.

2.What are the performance characteristics of Alloy Steel Casting?

Low alloy steel is a type of steel made by adding one or several alloying elements (manganese, silicon, vanadium, etc.) when smelting carbon structural steel. Low alloy steel can improve strength, impact toughness, corrosion resistance and not reduce the plasticity of steel. Because the total mass fraction of alloy elements is less than 5%, it is called low alloy steel.

Low alloy steel is added with a small amount of alloy elements. It is mainly used in construction, automobiles, mining machinery, agricultural machinery accessories and engineering structures. Low alloy steel is lighter than carbon structural steel, which can reduce the dead weight of the structure, save metal materials and extend the service life of the structure. At the same time, low alloy high-strength structural steel also has good toughness and weldability, and some also have the characteristics of corrosion resistance and low temperature resistance.

The alloying principle of low alloy steel is mainly to improve the strength of steel by using the solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the fine grain strengthening is used to reduce the toughness-brittleness transition temperature of steel to offset the adverse effect of carbonitride precipitation strengthening in steel to increase the toughness-brittleness transition temperature of steel, so that steel can obtain high strength while maintaining good low temperature performance. Low alloy steel has high yield strength, good plasticity and toughness, good welding performance and atmospheric corrosion resistance.
