Understanding the Composition and Applications of 34Cr4 Steel Grade

[ad_1] 34Cr4 is a quenched and tempered steel with a low carbon content and high strength. Its composition is as follows:

– Carbon: 0.30-0.37%
– Silicon: max 0.40%
– Manganese: 0.60-0.90%
– Phosphorus: max 0.025%
– Sulfur: max 0.035%
– Chromium: 0.90-1.20%

The addition of chromium provides good hardenability and high strength, making 34Cr4 suitable for applications such as gears, shafts, bolts, and studs in the automotive and mechanical engineering industries. This steel grade is often used in the construction of heavy-duty machinery and equipment where high strength and good wear resistance are required.

The mechanical properties of 34Cr4 include a high tensile strength and good toughness, as well as good hardenability and resistance to wear. It can be heat treated to achieve specific strength and hardness levels, making it a versatile material for various engineering applications.
