Examining the Metallurgical Composition of 35CrMo4 Steel

[ad_1] The chemical composition of 35CrMo4 steel typically includes:

– Carbon (C): 0.32-0.40%
– Silicon (Si): 0.17-0.37%
– Manganese (Mn): 0.40-0.70%
– Phosphorus (P): ≤ 0.025%
– Sulfur (S): ≤ 0.035%
– Chromium (Cr): 0.90-1.20%
– Molybdenum (Mo): 0.15-0.25%

The technical properties of 35CrMo4 steel include a high tensile strength, good toughness, and excellent wear resistance. It is often used in applications where high strength and impact resistance are required, such as in the construction of heavy machinery and automotive components.

The mechanical properties of 35CrMo4 steel include a tensile strength of 900-1200 MPa, a yield strength of 650-850 MPa, and a hardness range of 250-320 HB. The steel also exhibits good fatigue resistance and can be heat treated to further enhance its mechanical properties.
