The technical properties of 25CrMo4 steel grade include a tensile strength of 930-1080 MPa, a yield strength of 785-930 MPa, and an elongation of 11-12%. The steel also has a high fatigue strength and good impact resistance, making it suitable for use in highly stressed components and structures.
The chemical composition of 25CrMo4 steel grade is as follows:
– Carbon (C): 0.22-0.29%
– Silicon (Si): 0.15-0.50%
– Manganese (Mn): 0.60-0.90%
– Phosphorus (P): max 0.025%
– Sulfur (S): max 0.035%
– Chromium (Cr): 0.90-1.20%
– Molybdenum (Mo): 0.15-0.30%
These elements contribute to the steel’s high tensile strength, toughness, and excellent hardenability, making it suitable for quenching and tempering processes to achieve the desired mechanical properties.
Overall, 25CrMo4 steel grade offers a combination of strength, versatility, and machinability, making it a popular choice for various industrial and engineering applications.
