Understanding the Properties and Applications of 28Mn6 Steel Grade

The 28Mn6 steel grade is a low alloy high strength steel that is commonly used in various industries. It offers good tensile and yield strength, as well as excellent toughness and ductility. This steel grade is known for its high impact resistance and can withstand high stress and strain.

The mechanical properties of 28Mn6 steel grade include a minimum tensile strength of 780 MPa and a minimum yield strength of 590 MPa. It has a high elongation at break of 22% and a good impact strength at room temperature. This makes it suitable for applications where high strength and toughness are required, such as structural components, shafts, gears, and fasteners.

The technical properties of 28Mn6 steel grade include a density of 7.85 g/cm3 and a thermal conductivity of 46 W/m·K. It has a high melting point of 1420-1460°C and a specific heat capacity of 480 J/kg·K. These properties make it suitable for use in high temperature environments, such as in the manufacturing of heat exchangers and thermal power plants.

The chemical composition of 28Mn6 steel grade consists of carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), and residual elements like nickel (Ni), chromium (Cr), and copper (Cu). The typical composition ranges are as follows:

– Carbon (C): 0.25-0.33%
– Manganese (Mn): 1.20-1.50%
– Πυρίτιο (Si): 0,20-0,40%
– Φώσφορος (P): max 0,035%
– Θείο (S): max 0,035%

The presence of these elements contributes to the overall strength, toughness, and corrosion resistance of the steel grade.

Overall, 28Mn6 steel grade is a versatile and widely used material due to its excellent mechanical and technical properties. It is suitable for a variety of applications in industries such as automotive, construction, and manufacturing.
