45 steel grade is a high-quality carbon structural steel with good mechanical properties and excellent impact toughness. It is commonly used in high-performance applications such as gears, shafts, crankshafts, and spindles.
Mechanical Properties:
– Tensile Strength: 600 MPa
– Yield Strength: 355 MPa
– Elongation: 16%
– Hardness: 200 HB
Chemical Composition:
– Carbon (C): 0.42-0.50%
– Manganese (Mn): 0.50-0.80%
– Silicon (Si): 0.17-0.37%
– Phosphorus (P): ≤ 0.035%
– Sulfur (S): ≤ 0.035%
The combination of its mechanical properties and chemical composition makes 45 steel grade an ideal choice for high-performance applications where strength, toughness, and wear resistance are essential. It can be easily machined and welded, making it a versatile option for various industrial uses.
