I. Production process

Adopting advanced continuous casting and rolling technology, by precisely controlling the rolling temperature and cooling rate, the internal structure of the alloy steel bar is made more uniform and dense, effectively reducing the segregation problem that may occur in traditional processes. At the same time, an online flaw detection system is introduced to conduct all-round quality inspection on each alloy steel bar to ensure the stability of product quality.

II. Performance

1. Physical properties

• Density is 7.85g/cm³

• The thermal expansion coefficient is (11.5 - 13.5) × 10⁻⁶/℃

2. Mechanical properties

• Tensile strength reaches 650MPa

• Yield strength exceeds 450MPa

• Fatigue life is nearly 20% higher than before

While ensuring high strength, it has good plasticity and toughness, excellent cold bending performance, and can meet the processing needs of complex-shaped parts.

III. Application fields

1. Machinery manufacturing industry

It is often used to manufacture key parts such as high-precision shafts and gears. A certain machinery manufacturing enterprise uses a new type of 17MnB4 alloy steel bar to produce a transmission shaft. Under high speed and heavy load conditions, the operating stability is significantly improved, the failure rate is reduced by 30%, and the reliability and service life of the equipment are greatly improved.

2. Automobile parts production

It is widely used in the manufacture of key components of automobile chassis suspension systems, such as control arms and steering knuckles. A well-known automobile manufacturer uses upgraded 17MnB4 alloy steel bars to reduce the weight of chassis components by 15%, while improving collision safety performance by 20%, effectively promoting the lightweight and safety upgrade of automobiles.

3. Construction industry

In the manufacture of steel structure connection components in the construction industry, 17MnB4 alloy steel bars have also emerged. Its good welding performance and high strength characteristics ensure the firmness of steel structure connections and provide strong guarantees for the quality and safety of large-scale construction projects.

IV. Conclusion

With the continuous maturity of technology and the continuous expansion of application scope, 17MnB4 alloy steel bars will play a greater role in promoting the high-quality development of various industries and become an indispensable high-quality material in the field of industrial manufacturing.
