34CrNiMo6 Steel: A Trusted Choice for High-Stress Applications

The 34CrNiMo6 steel is commonly used in high-stress applications due to its excellent mechanical properties and chemical composition.

Mechanical properties of 34CrNiMo6 Steel:
– Tensile Strength: The steel has a high tensile strength ranging from 1100 to 1300 MPa, making it suitable for applications where there is a high amount of stress and strain.
– Yield Strength: It has a yield strength of around 900 MPa, indicating its ability to withstand a significant amount of stress before permanent deformation occurs.
– Impact Toughness: The steel exhibits good impact toughness, ensuring it can withstand sudden loads without fracturing.
– Fatigue Strength: 34CrNiMo6 steel has high fatigue strength, making it resistant to cracking and failure under cyclic loading conditions.

Chemical composition of 34CrNiMo6 Steel:
– Carbon (C): The steel contains a moderate amount of carbon, typically around 0.30-0.40%, which provides hardness and strength.
– Manganese (Mn): Manganese is present in trace amounts, typically less than 0.80%, to enhance the hardenability of the steel.
– Silicon (Si): Silicon is present in small quantities, usually up to 0.40%, which helps improve the steel’s strength and robustness.
– Chromium (Cr): The steel contains chromium in the range of 0.90-1.20%, contributing to its high hardenability and resistance to corrosion.
– Nickel (Ni): Nickel is present in significant quantities, typically between 1.30-1.70%, which improves the steel’s toughness, ductility, and resistance to scaling.
– Molybdenum (Mo): The steel contains molybdenum in the range of 0.15-0.30%, which enhances its strength and toughness while improving its resistance to pitting and crevice corrosion.

Overall, the mechanical properties and chemical composition of 34CrNiMo6 steel make it a trusted choice for high-stress applications. Its combination of high tensile strength, yield strength, impact toughness, fatigue strength, and the presence of alloying elements like nickel and chromium make it suitable for demanding environments where strength and durability are vital.
