1.2311 (40CrMnNiMo8-6-4) Steel

Chemical composition

This steel grade exhibits excellent strength and toughness, making it suitable for a wide range of demanding applications. Its high tensile strength allows it to withstand heavy loads and stresses without deformation or failure, while its good toughness enables it to absorb impact energy and resist cracking. This combination of strength and toughness gives 1.2311 steel the ability to perform reliably in harsh working conditions.

In addition to its mechanical properties, 1.2311 steel also offers good hardenability. It can be easily hardened through heat treatment processes, such as quenching and tempering, to achieve the desired hardness levels. This allows for the production of components with high wear resistance and durability, which is particularly important in applications where abrasion and wear are common.

Another notable characteristic of 1.2311 steel is its excellent machinability. It can be readily machined using conventional machining techniques and tools, resulting in high-quality finished parts with smooth surfaces and tight tolerances. This machinability makes it a preferred choice for manufacturers who require efficient and cost-effective production processes.

Furthermore, 1.2311 (40CrMnNiMo8-6-4) Steel has good dimensional stability. It maintains its shape and dimensions during heat treatment and under varying operating conditions, ensuring the accuracy and reliability of the manufactured components. This property is crucial in applications where precise tolerances are required, such as in the production of molds, dies, and precision machinery parts.

The alloy composition of 1.2311 steel, which includes chromium, manganese, nickel, molybdenum, and other elements, contributes to its overall performance. These elements work together to enhance the steel's strength, toughness, hardenability, and corrosion resistance. The balanced alloying also provides good weldability, allowing for the fabrication of complex structures and assemblies.

In the field of plastic injection molding, 1.2311 steel is widely used for the production of molds. Its high strength and wear resistance enable the molds to withstand the repeated injection cycles and the abrasive action of the plastic material, resulting in long service life and high productivity.
