TAGS: EN 10083-1 | steel grade | 34Cr4 | alloy steel |
EN 10083-1 is a European standard that specifies the technical delivery conditions for non-alloy and alloy steels for quenching and tempering. It is part of the EN 10083 series, which covers various types of steel grades for different applications.
EN 10083-1 specifically focuses on the general technical delivery conditions for both non-alloy and alloy steels intended for heat treatment after quenching and tempering. These steels are typically used for the manufacture of machine parts, gears, shafts, and other components that require specific mechanical properties, such as high strength, toughness, and wear resistance.
EN 10083-1 provides requirements for the chemical composition, mechanical properties, hardness values, and other relevant characteristics of the steels. It includes guidelines for heat treatment processes such as quenching and tempering, which are crucial for achieving the desired mechanical properties.
EN 10083-1 covers a wide range of steel grades, including both non-alloy steels and alloy steels with varying compositions and properties. The specific grade designation can be found within the standard, along with the corresponding requirements and specifications for that particular grade.
EN 10083-1 Grade 34Cr4 is a specific grade of steel specified in the EN 10083-1 standard. This grade falls under the category of non-alloy special steels for quenching and tempering.
The designation "34Cr4" indicates the composition and properties of the steel. Here is a breakdown:
"34" refers to the approximate carbon content, which is around 0.30-0.37%.
"Cr" represents chromium as an alloying element, typically ranging from 0.90-1.20%.
The number "4" signifies that it is the fourth grade within the 34Cr range.
Grade 34Cr4 is known for its good hardenability and high strength. It is commonly used in the manufacturing of gears, shafts, and other components that require elevated mechanical properties after the quenching and tempering process.
Steel 34Cr4 is suitable for mean loaded parts and mean heat-treatment sections in vehicle manufacturing, engine and machine engineering (e.g. transmission parts, shafts, axles), Lowest working temperature -25 °C.
