Understanding the Properties and Composition of 41Cr4 Steel Grade

[ad_1] The 41Cr4 steel grade is a widely used alloy steel that is known for its high strength, toughness, and hardness. It belongs to the DIN 1.7035 material group, which is commonly used in manufacturing various mechanical components and tools.

The technical properties of 41Cr4 steel grade include a high tensile strength of 900 – 1100 MPa, a yield strength of 600 MPa, and a high hardness level of 200 – 250 HB. This steel grade also has good machinability and weldability, making it suitable for various machining and fabrication processes.

The chemical composition of 41Cr4 steel grade includes:

– Carbon (C): 0.38 – 0.45%
– Silicon (Si): 0.40%
– Manganese (Mn): 0.60 – 0.90%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.035% max
– Chromium (Cr): 0.90 – 1.20%

These elements contribute to the overall strength, toughness, and hardenability of the steel, making it suitable for high-stress applications in the automotive, machinery, and construction industries.

Overall, the 41Cr4 steel grade is known for its excellent mechanical properties and composition, making it a popular choice for various applications that require high strength and hardness.
