Chemical Composition:
– Carbon (C): 0.32-0.39%
– Silicon (Si): 0.40% max
– Manganese (Mn): 0.50-0.80%
– Phosphorus (P): 0.025% max
– Sulfur (S): 0.020% max
– Nickel (Ni): 1.50-2.00%
– Chromium (Cr): 1.30-1.70%
– Molybdenum (Mo): 0.15-0.30%
The addition of nickel, chromium, and molybdenum contributes to the steel’s high hardenability and strength, while the low carbon content ensures good weldability and toughness.
Mechanical Properties:
– Tensile Strength: 1100-1300 MPa
– Yield Strength: 900-1100 MPa
– Elongation: 10-15%
– Hardness: 300-350 HB
Uses:
35NiCrMo6 KB steel is commonly used in the construction of heavy-duty gears, shafts, crankshafts, and other components in the automotive, aerospace, and machinery industries. Its high strength and toughness make it suitable for applications where high stress and wear resistance are required, such as in gearboxes, axles, and hydraulic machinery.
In summary, 35NiCrMo6 KB steel is a high-strength low-alloy steel known for its excellent hardenability and toughness. With its specific chemical composition and mechanical properties, it is well-suited for the production of heavy-duty machine parts and components that require high strength, wear resistance, and good weldability.
