– Impact Resistance: The 45WCrV8KU steel grade demonstrates good impact resistance, making it suitable for applications where sudden loads are encountered.
Chemical Composition:
– Carbon (C): The carbon content in the 45WCrV8KU steel grade is typically around 0.40%-0.50%. This carbon content provides strength and hardness to the steel.
– Chromium (Cr): The steel grade contains about 0.90%-1.10% chromium, which enhances the hardenability and wear resistance of the steel.
– Vanadium (V): The addition of vanadium ranging from 0.15%-0.25% improves the toughness and strength of the steel.
– Tungsten (W): The steel grade includes tungsten in the range of 1.5%-2.0%, which contributes to its high temperature strength and wear resistance.
– Manganese (Mn): The manganese content is usually limited to a maximum of 0.40% to maintain good machinability.
– Silicon (Si): Silicon is added in trace amounts (around 0.15% maximum) to improve the steel’s hardenability and strength.
– Phosphorus (P) and Sulfur (S): These elements are kept at low levels (0.03% max) to ensure good weldability and prevent brittleness.
Overall, the 45WCrV8KU steel grade offers exceptional mechanical properties, including high tensile and yield strength, excellent hardness, and good impact resistance. Its chemical composition, with a balanced combination of carbon, chromium, vanadium, tungsten, and other elements, contributes to its superior performance in industrial manufacturing applications.
