35CrMoA alloy round steel is an alloy structural steel with excellent mechanical properties and heat treatment properties. It is widely used in the manufacture of important structural parts that bear high loads and high stresses. The material has high durability and creep strength at high temperatures, as well as good low-temperature impact toughness, making it suitable for a variety of harsh working environments.

35CrMoA alloy round steel is a highly favored high-performance material in the field of mechanical engineering and stands out for its excellent comprehensive properties. It plays a core role in the manufacturing of many key components. It is suitable for working conditions that have strict requirements on strength, toughness, fatigue resistance, high temperature resistance, and high pressure resistance. It provides high-end equipment for petrochemical, electric power, aerospace and other industries. Solid and reliable foundation support.

Material properties:

Combination of high strength and high toughness: After a reasonable heat treatment process, 35CrMoA alloy round steel exhibits impressive high strength and can easily handle the huge pressure brought by heavy loads and high pressures. It also has excellent toughness and can effectively buffer impact loads. , to avoid brittle fracture of components under extreme working conditions and ensure safe and stable operation of equipment.

Excellent high-temperature resistance: The addition of alloy elements such as chromium and molybdenum gives it extraordinary high-temperature resistance. In high-temperature environments, the material's microstructure is stable and its mechanical properties decay slowly. It can serve for a long time in high temperatures such as petrochemical equipment. High temperature and high pressure areas such as reaction vessels and steam pipes of thermal power equipment.

Good fatigue resistance: In complex working conditions where alternating stress frequently acts, such as rotating parts of aerospace engines, main shafts of wind turbines, etc., this alloy round steel can effectively suppress the occurrence and development of fatigue cracks by virtue of its excellent fatigue resistance. Expansion, greatly extending the service life of key components, reducing equipment downtime and maintenance time, and improving operating efficiency.

Excellent processing performance: Before final heat treatment, the material has appropriate hardness and is easy to perform machining operations such as cutting and forging. It can be accurately formed into parts of various complex shapes to meet diversified design needs, and the processed surface quality is excellent, which will provide the basis for subsequent work. The finishing process lays a good foundation.

Things to note

When welding, the weldability of 35CrMoA alloy round steel is poor. It needs to be preheated to 150~400℃ before welding, and heat treatment is required after welding to eliminate stress.

During use, care should be taken to avoid overheating and overcooling to prevent cracks and deformation.

35CrMoA alloy round steel has become an indispensable and important material in many industries due to its excellent performance and wide range of applications.
