EN DIN 34CrNiMo6 Steel

 

34CrNiMo6 is a quenched and tempered steel, which is standardized as EN10083-3. This steel is commonly used in high-strength bolts, bearings, and gears, among other mechanical parts.

 

The specific chemical composition is as follows:

Carbon (C): 0.30-0.38%

Silicon (Si): 0.40% maximum

Manganese (Mn): 0.50-0.80%

Phosphorus (P): 0.025% maximum

Sulfur (S): 0.035% maximum

Chromium (Cr): 1.30-1.70%

Nickel (Ni): 1.40-1.70%

Molybdenum (Mo): 0.15-0.30%

 

The steel has a tensile strength of 1000-1250MPa, a yield strength of 850-1080MPa, and a fracture elongation of 10-13%.

 

It is available in a quenched or tempered state.

 

Advantages:

1. High strength and good toughness

2. Versatile and can be used in a variety of mechanical parts

3. Can be further improved through heat treatment

 

Disadvantages:

1. Relatively high price

2. Easily softened or annealed at high temperatures

3. Some areas require strict processing requirements for the steel

 

The most common forms of the steel include round bars, square bars, steel plates, and steel tubes.

 

Comparison of national grades:

Chinese Grade: 34CrNiMo6

US Grade: 4340

German Grade: 1.6582

British Grade: 826M40

Japanese Grade: SNCM439

 

In summary, 34CrNiMo6 is a widely used high-strength quenched and tempered steel in mechanical parts. It has good toughness and high strength, making it suitable for high workloads. However, the steel is relatively expensive and can be softened or annealed at high temperatures, so strict processing control and heat treatment are required.
