Superior Materials 41cr4 Steel Mechanical Properties - China

41Cr4 steel is an alloy structural steel, and the implementation standard is EN 10083-3 - It is used in the quenched and tempered state and has high strength, toughness and hardenability.

The following is a detailed introduction to its mechanical properties: 41Cr4 steel mechanical properties

Quenched and tempered state (quenched and tempered state)

• Tensile strength: σb≥800-1000 MPa.

Tensile strength is the maximum stress value reached by the material from the beginning to the fracture during the tensile process.

This strength index ensures that 41Cr4 steel will not break easily when subjected to large tensile forces, and is suitable for manufacturing mechanical parts that bear large loads.

• Yield strength: σs≥600-800 MPa.

Yield strength refers to the stress when the material begins to produce obvious plastic deformation.

In engineering applications, when the stress on the parts reaches the yield strength, irreversible deformation will occur, so the yield strength is also an important indicator for measuring the bearing capacity of the material.

• Elongation: δ5≥9%.

The elongation reflects the plastic deformation ability of the material at the time of tensile fracture.

The greater the elongation, the better the plasticity of the material.

When subjected to external force, it can deform greatly without breaking.

This is a very important performance for some parts that need to absorb energy or may deform to a certain extent during the force process.

• Section shrinkage: ψ≥40%.

Section shrinkage is also one of the indicators to measure the plasticity of the material.

It indicates the ratio of the area of ​​the reduced section to the original section area after the specimen is broken.

A higher section shrinkage indicates that the material can withstand greater plastic deformation before breaking.

• Impact toughness: Impact absorption energy AKV≥47J (normal temperature).

Impact toughness reflects the ability of the material to resist impact loads.

For some parts that may be subjected to impact loads during work, such as gears, shafts, etc., good impact toughness can prevent brittle fracture of the parts under impact.
