Steel is essentially iron and carbon alloyed with certain additional elements.

And the low alloy steel is 345MPa. The carbon content of steel reaches a maximum of 1.5 percent.

ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them. There are generally two categories of alloy steel: low alloy and high alloy.

Alloy steels are designated by AISI four-digit numbers. 25-45 70-110 110 min. 4140 Steel Uses. Alloying different elements changes the properties of the steel pretty drastically. Steel is an alloy, consisting mainly of iron, with a carbon content of 0.2% to 2.1% by weight. High-Alloy Steel.

manganese, silicon, nickel, titanium, copper, chromium, and aluminum) in varying proportions in order to manipulate the steel's properties, such as its hardenability, corrosion resistance, strength, formability, weldability or ductility.

These alloying elements are added to increase strength, hardness, wear resistance, and toughness. 52100 steel is a high carbon chromium alloy steel that has a density of 7.81 g/cm 3 (0.282 lb/in 3). These alloys typically comprise 1 to 5 percent of the steel's content and are added based on their ability to provide a very specific attribute.


These steels are not consid-ered alloy steels, even though their desired properties are achieved by the Compare two types of steel, use it can decrease steel size and make the weight get lower. Alloy Steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. The process of alloying is used to change the chemical composition of steel and improve its properties over carbon steel or adjust them to meet the requirements of a particular application. Alloy steels may be classified into two groups: low alloy steel and high alloy steel.

4140 Steel properties and heat treat as below. AISI 4340 steel is an ultra-high strength medium carbon low alloy steel, material properties, heat treatment, equivalent, hardness chart, density, machinability 1.7225 Steel Characteristics. 4130 Alloy Steel.
Alloy steel is a class of steel that, in addition to carbon, is alloyed with other elements, ranging from 1 wt.% to 50 wt.%, which are used to enhance the material’s various properties [1].. Service design requirements also require other more basic properties such as elevated temperature proof strength (sometimes tensile strength) and impact/toughness resistance.
