Description:
41Cr4 is a steel grade that belongs to the class of alloy steels. It is a versatile material that offers a combination of excellent mechanical properties and good formability. The chemical composition of 41Cr4 includes a high percentage of chromium, which provides enhanced hardness and strength.

The ultimate tensile strength of 41Cr4 steel is in the range of 900 to 1100 MPa, making it highly resistant to breakage. This property enables its use in applications that require high strength and durability, such as in the manufacturing of automotive parts, industrial equipment, and machinery components.

The yield strength of 41Cr4 steel ranges from 600 to 800 MPa, indicating its ability to withstand significant loads without permanent deformation. This characteristic makes it suitable for applications where structural integrity and reliability are crucial.

In terms of ductility, 41Cr4 steel exhibits an elongation of 16 to 20%, indicating its ability to deform significantly without fracturing. Additionally, it has a reduction in area of 40 to 45%, which implies good deformability and resistance to local failure.

The hardness of 41Cr4 steel, measured using the Brinell hardness (HB) test, falls in the range of 170 to 220 HB. This level of hardness ensures excellent wear resistance, making it suitable for applications in which the material is subjected to abrasive forces or fatigue.

Furthermore, 41Cr4 steel possesses good impact toughness, with values ranging from 27 to 31 Joules. This property allows it to withstand sudden loads or shocks, making it useful for applications where impact resistance is vital.

Overall, 41Cr4 steel grade exhibits a unique combination of mechanical properties, including high strength, good ductility, excellent wear resistance, and impact toughness. These characteristics make it a versatile material suitable for various industrial applications, particularly those requiring durable and unbreakable components.
