Excellent properties of 35CrMnSiA alloy steel

35CrMnSiA alloy steel is an important structural steel and is widely used in the manufacturing of engineering machinery, auto parts, aerospace devices and other fields. This article reviews the physical properties of 35CrMnSiA alloy steel, including its mechanical properties, thermal properties, electromagnetic properties and corrosion resistance.

1.Mechanical properties
35CrMnSiA alloy steel has excellent mechanical properties. After heat treatment, the yield strength of the alloy can reach 1200 MPa, the tensile strength can reach 1400 MPa, and the elongation can reach more than 10%. This makes it perform well under high strength and load conditions.

2. Thermophysical properties
35CrMnSiA alloy steel has high thermal conductivity and thermal expansion coefficient, and is suitable for working in high temperature environments. At the same time, the alloy has good heat treatment properties, and the structure and properties of the material can be adjusted by controlling the heat treatment process.

3.Electromagnetic properties
35CrMnSiA alloy steel has good magnetic properties and is suitable for applications in electromagnetic equipment and sensors. This alloy can be used to manufacture high-precision magnetic sensors, motor cores, etc., and has broad market prospects.

4. Corrosion resistance
35CrMnSiA alloy steel has good corrosion resistance and good durability in common environments (such as atmosphere, water, etc.). However, in corrosive media such as strong acid and strong alkali, the corrosion resistance of this alloy is relatively poor, and corresponding protective measures need to be taken.

5. Wear performance
35CrMnSiA alloy steel has good wear resistance and is suitable for manufacturing wear-resistant parts. Its wear mechanism mainly includes abrasive wear and surface fatigue wear, and its wear resistance can be improved through reasonable heat treatment and surface treatment.
