Product Tags

16MnCr5 alloy steel is a widely used low carbon alloy steel, which is particularly suitable for the manufacture of shaft and gears parts due to its excellent strength and wear resistance. The material can be hardened on the surface through carburizing treatment, while maintaining good toughness inside, which is suitable for high load and long working environment.

Chemical composition

The chemical composition of 16MnCr5 alloy steel has low carbon and high manganese and chromium content. This alloy design enables the steel to obtain very high surface hardness after carburizing while maintaining core toughness. Its typical chemical composition is as follows:

Carbon (C): 0.14%-0.19%
Silicon (Si): ≤ 0.40%
Manganese (Mn): 1.00%-1.30%
Chromium (Cr): 0.80%-1.10%
Sulfur (S): ≤ 0.035%
Phosphorus (P): ≤ 0.035%

Mechanical properties

After carburizing and heat treatment, 16MnCr5 alloy steel shows extremely excellent mechanical properties, especially for high stress parts such as gears. The following are typical mechanical properties:

Tensile strength: 900-1200 MPa
Yield strength: ≥ 650 MPa
Elongation: 8%-12%
Impact toughness: ≥ 35 J (at 20°C)
Hardness: The surface hardness can reach 58-62 HRC after carburizing and quenching

Application of gears

Automotive industry: In automobile manufacturing, 16MnCr5 alloy steel gears are often used in key components such as gearboxes, drive shafts and differentials. These components need to maintain good wear resistance and stability under high load and long-term operation. The high surface hardness of 16MnCr5 after carburizing treatment ensures the long-term service life and reliability of automotive gears.

Construction machinery: 16MnCr5 alloy steel materials are widely used in the manufacture of gears for construction and mining machinery. These equipment usually work in harsh environments, requiring gears to have high strength and high wear resistance, while also being able to resist impact loads. 16MnCr5 alloy steel gears ensure efficient operation of equipment under harsh working conditions through their excellent hardness and toughness.

Industrial equipment: 16MnCr5 alloy steel gears are also widely used in various industrial equipment such as reducers, transmissions and pumps. Especially in the environment of continuous work and heavy load transmission, 16MnCr5 alloy steel forged gears show good durability and fatigue resistance, and are suitable for long-term high-intensity work.

Wind power and energy fields: 16MnCr5 alloy steel gears are also widely used in wind power generation equipment. Wind turbine gearboxes require high strength and long life, and 16MnCr5 alloy steel, after carburizing, has a high-hardness surface layer and a tough core structure, which is suitable for coping with complex load conditions.
