The 41Cr4 steel grade is a medium carbon steel alloy primarily used in manufacturing various components requiring high strength, toughness, and wear resistance. Its unique characteristics make it suitable for applications such as gears, shafts, crankshafts, connecting rods, and other highly stressed mechanical parts.

With a tensile strength range of 780-930 MPa and a yield strength range of 620-780 MPa, 41Cr4 exhibits excellent mechanical strength. Additionally, it has a good elongation range of 14-21% and a high impact strength of at least 35 J/cm², showcasing its ability to withstand heavy loads and absorb shock.

The steel’s chemical composition plays a vital role in determining its properties. The carbon content of 0.38-0.45% provides the desired strength and hardness, while the presence of chromium (0.90-1.20%) enhances its wear resistance and corrosion resistance. Manganese (0.60-0.90%) helps improve hardenability and machinability, while silicon (<= 0.40%) aids in deoxidation and contributes to better strength. Lower levels of phosphorus (<= 0.025%) and sulfur (<= 0.035%) assure good weldability and avoid brittleness. In conclusion, the 41Cr4 steel grade exhibits a unique combination of high mechanical strength, toughness, and wear resistance, making it an ideal choice for demanding applications in the automotive, machinery, and general engineering industries. Its versatile nature, coupled with its excellent qualities, positions it as a metallurgical marvel. 41Cr4 Steel grade 1698431480
