CK45 steel is a type of carbon steel that is commonly used in heavy machinery and automotive industries due to its excellent mechanical properties and chemical composition.
Mechanical Properties:
– Tensile Strength: 600-800 MPa
– Yield Strength: 355 MPa
– Elongation: 16%
– Hardness: 170-210 HB
– Impact Energy: ≥ 34 J at 20 °C
Chemical Composition (in weight %):
– Carbon (C): 0.42-0.50%
– Silicon (Si): 0.15-0.35%
– Manganese (Mn): 0.50-0.80%
– Phosphorus (P): ≤ 0.025%
– Sulfur (S): ≤ 0.025%
CK45 steel offers a high tensile strength and good yield strength, making it suitable for heavy machinery and automotive applications that require strong and durable materials. Its moderate carbon content provides good weldability and machinability, making it easy to work with during fabrication and assembly processes. Additionally, CK45 steel has good impact resistance, allowing it to withstand heavy loads and vibrations commonly found in these industries.
The chemical composition of CK45 steel ensures a balanced combination of strength, toughness, and corrosion resistance. The controlled levels of carbon, silicon, manganese, phosphorus, and sulfur provide optimal properties for heavy machinery and automotive applications. The low sulfur and phosphorus content help to reduce the risk of brittleness and improve the steel’s weldability and machinability.
In summary, CK45 steel is a steadfast choice for heavy machinery and automotive industries due to its excellent mechanical properties, including high strength, good yield strength, and impact resistance, as well as its balanced chemical composition, providing good weldability and machinability.
