An In-Depth Look at the Chemical Composition of 41Cr4 Steel Grade

[ad_1] The 41Cr4 steel grade is a low-alloy steel that contains chromium and has good hardenability and machinability. Its chemical composition is as follows:

– Carbon (C): 0.38-0.45%
– Silicon (Si): 0.40% max
– Manganese (Mn): 0.60-0.90%
– Phosphorus (P): 0.025% max
– Sulfur (S): 0.035% max
– Chromium (Cr): 0.90-1.20%

The presence of chromium in this steel grade provides good hardenability, while the carbon content contributes to its overall strength and wear resistance. The manganese content helps improve the steel’s toughness and hardenability. Additionally, the controlled levels of phosphorus and sulfur help maintain the steel’s machinability.

In terms of mechanical properties, the 41Cr4 steel grade exhibits the following characteristics:
– Tensile strength: 1020-1110 MPa
– Yield strength: 890-930 MPa
– Elongation: 10-12%
– Hardness: 230-290 HB

These mechanical properties make the 41Cr4 steel grade suitable for various applications, including the manufacturing of components such as gears, shafts, and other machine parts that require high strength and wear resistance.

Overall, the 41Cr4 steel grade’s chemical composition and mechanical properties make it a versatile and reliable material for engineering applications that require good hardenability, strength, and machinability.
