High-strength bolts are working under high strength and high resistance, and the material has a crucial impact on the performance of high-strength bolts. Choosing the right material is the key to ensure the normal work of high-strength bolts.
High strength bolt material selection guide:
1. 40Cr Steel
40Cr is a commonly used high-strength material, with a certain toughness and hardness, suitable for striking a balance between strength and toughness, and the price is relatively low.
2. 45 Steel
45 For the manufacture of nut and stud rods. Its hardness and wear resistance are relatively good, but it is relatively brittle
3. 35CrMo Material
35CrMo has good strength and toughness, so it is widely used in the manufacture of high-strength bolts that are demanding and need to withstand greater pressure.
4. 20CrMoTi Carbon Steel
20CrMoTi is a titanium alloy strengthening material, which has the characteristics of light material, corrosion resistance and wear resistance. Relying on the advantages of titanium alloys, 20CrMoTi has relatively excellent strength and toughness, and also has good corrosion resistance and wear resistance.
