34CrNiMo6 Steel Grade: Leading the Way in Heat Treatment Capabilities

34CrNiMo6 steel grade is a versatile and highly alloyed steel that is primarily used in the manufacture of high-strength components. It has excellent heat treatment capabilities, making it a preferred choice for applications that require high tensile strength, toughness, and resistance to wear and fatigue.

The chemical composition of 34CrNiMo6 steel grade is as follows:

– Carbon (C): 0.30-0.38%
– Silicon (Si): ≤0.40%
– Manganese (Mn): 0.50-0.80%
– Phosphorus (P): ≤0.025%
– Sulfur (S): ≤0.035%
– Chromium (Cr): 1.30-1.70%
– Nickel (Ni): 1.30-1.70%
– Molybdenum (Mo): 0.15-0.30%

These alloying elements significantly contribute to the overall mechanical properties of the steel grade. The combination of high carbon content and alloying elements enhances the strength and hardenability of 34CrNiMo6 steel. It also provides excellent wear and impact resistance while maintaining good toughness.

The mechanical properties of 34CrNiMo6 steel grade after appropriate heat treatment include:

– Tensile strength: 1000-1400 MPa
– Yield strength: ≥900 MPa
– Elongation: ≥14%
– Reduction in area: ≥45%
– Impact energy (Charpy V-notch): ≥40 J at -40°C (-40°F)

These mechanical properties make 34CrNiMo6 steel grade suitable for a wide range of applications, including high-stress gears, shafts, bolts, and other critical components subjected to heavy loads and harsh operating conditions. Its excellent heat treatment capabilities further contribute to its overall strength and durability.

In summary, 34CrNiMo6 steel grade is a leading choice for applications that require high tensile strength, toughness, and resistance to wear and fatigue. Its chemical composition, combined with appropriate heat treatment, allows it to achieve exceptional mechanical properties, making it a reliable and versatile steel grade in various industries.
