The 805M20 steel grade is a low carbon case hardening steel with high tensile strength and good wear resistance. Its mechanical properties and chemical composition are important for understanding its performance in various applications.
Mechanical Properties:
– Tensile Strength: 775-925 MPa
– Yield Strength: 525-675 MPa
– Elongation: 10-13%
– Hardness: 217-277 HB
These mechanical properties make 805M20 suitable for applications requiring high strength, such as gears, shafts, and studs.
Chemical Composition:
– Carbon: 0.17-0.23%
– Manganese: 0.70-1.00%
– Silicon: 0.10-0.40%
– Phosphorus: 0.035% max
– Sulfur: 0.040% max
The chemical composition of 805M20 steel grade contributes to its hardenability and strength, while also providing good weldability and machinability.
Understanding the mechanical properties and chemical composition of 805M20 steel grade is essential for selecting the right material for a specific application and ensuring its performance and reliability.
