1. Definition of 35mf4.
35MF4 is a low-alloy steel with a carbon content of 032-0.39% with a chromium content of 080-1.10%, molybdenum content of 015-0.25% with a manganese content of 110-1.40%, sulfur content does not exceed 0025%, phosphorus content does not exceed 0035%, the rest is iron and impurities.
2. Mechanical properties of 35mf4.
1.Strength: 35MF4 has a yield strength of 580-900MPa, a tensile strength of 780-1050MPa, and an elongation of 11-18%.
2.Hardness: The hardness value of 35MF4 is 190-230HB.
3.Toughness: 35mF4 has good toughness and can still maintain a certain plastic deformation ability under high-strength conditions.
3. Heat treatment of 35MF4.
1.Solution treatment: 35mF4 is heated to 860-900°C, and cooled to air temperature after holding for a certain time. Solution treatment can make the alloying elements evenly dissolved in the matrix, and improve the plasticity and toughness of the alloy steel.
2.Quenching treatment: 35MF4 after solution treatment is quickly cooled to 160-220 °C of the medium temperature, and cooled to room temperature after holding for a certain time. Quenching can improve the hardness and strength of alloy steel.
3.Tempering treatment: heat the quenched 35MF4 to 200-450 °C, keep it warm for a certain time and then cool it to room temperature. The tempering treatment can eliminate the internal stress of quenching and improve the toughness and ductility of alloy steel.
Fourth, the application field of 35mf4.
Due to its excellent mechanical properties and wear resistance, 35MF4 is widely used in automobile manufacturing, construction machinery manufacturing, shipbuilding and other fields. In automobile manufacturing, 35MF4 is often used to manufacture steering rods, crankshafts, connecting rods and other parts. In construction machinery manufacturing, 35MF4 is often used to manufacture wear-resistant parts such as hinge rods and bucket teeth.
Summary: 35MF4 is a commonly used low-alloy steel material with excellent mechanical properties and wear resistance. With proper heat treatment, its hardness, strength and toughness can be further improved. Due to its wide range of applications, the study and understanding of 35mf4 is of great significance.
