Understanding the Composition and Characteristics of 34CrNiMo6 Steel Grade

[ad_1] The 34CrNiMo6 steel grade is a low-alloy steel with high strength and toughness. It is commonly used in applications where high tensile strength, fatigue resistance, and good hardenability are required. The composition of 34CrNiMo6 steel typically includes the following elements:

– Carbon (C): 0.30-0.38%
– Silicon (Si): 0.10-0.40%
– Manganese (Mn): 0.50-0.80%
– Phosphorus (P): Max 0.035%
– Sulfur (S): Max 0.035%
– Chromium (Cr): 1.30-1.70%
– Nickel (Ni): 1.30-1.70%
– Molybdenum (Mo): 0.15-0.30%

In addition to the chemical composition, the 34CrNiMo6 steel grade also has specific mechanical properties. These include a tensile strength of 1000-1200 MPa, a yield strength of 800-950 MPa, and an elongation of 13-16%. The steel grade also has good impact toughness and can be heat treated to achieve different levels of hardness and strength.

Overall, the 34CrNiMo6 steel grade is known for its excellent combination of high strength, toughness, and hardenability, making it suitable for a wide range of industrial applications such as gears, shafts, and other components that require high performance under heavy loads.
