– Carbon (C): 0.42-0.50%
– Manganese (Mn): 0.60-0.90%
– Silicon (Si): 0.10-0.35%
– Phosphorus (P): 0.040% max
These elements play a vital role in determining the mechanical properties and the overall strength and versatility of the steel grade. The carbon content provides strength and hardness to the steel, while manganese enhances its hardenability, improves its toughness, and increases its resistance to wear and abrasion. Silicon helps to deoxidize the steel and improves its strength and fluidity during the manufacturing process. Phosphorus, in small amounts, aids in increasing the strength and toughness of the steel, although excessive phosphorus content can cause brittleness.
The mechanical properties of 080M46 steel grade, resulting from its chemical composition and various heat treatment processes, include high tensile strength, good ductility, and excellent machinability. It can be easily formed, welded, and machined using conventional methods. This combination of mechanical properties makes it suitable for a wide range of applications, including shafts, gears, axles, spindles, and other high-stress components in automotive, engineering, and industrial sectors.
It is important to note that the technical and mechanical properties of steel grades can also be influenced by other factors such as the manufacturing process, heat treatment, and any additional alloying elements present. Therefore, it is recommended to refer to specific manufacturer’s datasheets or ASTM/BS/EN standards for detailed and accurate information about the mechanical and technical properties of 080M46 steel grade.
