– Carbon (C): 0.30-0.37%
– Silicon (Si): 0.40% max
– Manganese (Mn): 0.60-0.90%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.035% max
– Chromium (Cr): 0.90-1.20%
These elements contribute to the overall mechanical properties of the steel, including its strength, hardness, and wear resistance.
The mechanical properties of 34Cr4 KB steel grade may include:
– Tensile strength: 1000-1200 MPa
– Yield strength: 800-1000 MPa
– Elongation: 10-15%
– Hardness: 27-35 HRC
These properties make 34Cr4 KB steel grade suitable for applications requiring high strength and hardness, such as in the manufacturing of gears, shafts, and other mechanical components.
