EN 10083-1 is a European standard that specifies the technical delivery conditions for non-alloy and alloy steels for quenching and tempering. It provides guidelines for the production, testing, inspection, and delivery of these steels.
EN 10083-1 covers a wide range of steel grades used in various industries such as automotive, machinery, and construction. It includes both non-alloy steels and alloy steels with different compositions and properties. The steels are intended for heat treatment after quenching and tempering to achieve the desired mechanical properties.
EN 10083-1 specifies requirements for the chemical composition of the steels, including elements such as carbon, manganese, silicon, phosphorus, sulfur, chromium, molybdenum, and others. It also sets limits on the permissible deviations in the chemical composition.
EN 10083-1 Mechanical properties, such as tensile strength, yield strength, elongation, and impact energy, are defined in the standard. Hardness values are specified to ensure the steels meet the required hardness levels after the heat treatment process. Other characteristics, including grain size, surface quality, and internal soundness, are also addressed.
EN 10083-1 provides guidelines for heat treatment processes, such as quenching and tempering, to achieve the desired properties in the steels. It outlines parameters for heating and cooling rates, soaking temperatures, and durations of each stage of the heat treatment process.
EN 10083-1 ensures that the delivered steels meet specific quality standards and can be processed effectively for their intended applications. Manufacturers and users of steel products refer to this standard to ensure compliance with the specified technical requirements and to guarantee the consistent quality of the produced materials.
EN 10083-1 Grade 34CrNiMo6 is a specific grade of steel specified in the EN 10083-1 standard. This grade falls under the category of alloy special steels for quenching and tempering.
Grade 34CrNiMo6 is characterized by the following composition:
Approximate carbon content: 0.30-0.38%
Chromium (Cr): 1.30-1.70%
Molybdenum (Mo): 0.15-0.30%
Nickel (Ni): 1.30-1.70%
This alloy steel grade exhibits high strength, toughness, and hardenability. It is commonly used in applications that require excellent fatigue resistance, such as heavy-duty gears, shafts, and components subjected to dynamic loads.
EN 10083-1 stipulates the technical delivery conditions for Grade 34CrNiMo6, including requirements for chemical composition, mechanical properties, hardness values, and other relevant characteristics. The standard ensures consistent quality and enables proper processing and utilization of the steel in various industries.
Mechanical properties specified in the standard include minimum and maximum values for tensile strength, yield strength, elongation, and impact energy. Hardness values are also defined to ensure the desired hardness levels can be achieved through appropriate heat treatment processes.
Heat treatment guidelines are provided to achieve the desired properties in the steel. Processes such as quenching and tempering are detailed, specifying parameters such as heating and cooling rates, soaking temperatures, and durations for each stage of the heat treatment process.
Steel 34CrNiMo6 is suitable for high loaded parts (also large forged parts) with high heat-treatment sections and favorable toughness properties in aircraft and heavy-vehicle construction, machine engineering (e.g. propeller shafts, connecting rods, transmission shafts). Lowest working temperature -40 °C.As a bright steel product it is used in the form of bars, bright, straight, in different conditions (see DIN EN 10277).
