Given the immense variety of steel, with properties tailored for everything from skyscrapers to surgical scalpels, a universal classification system is not just helpful—it's essential. First published in 1988, the current version, EN 10020:2000, remains widely adopted across Europe and has been harmonized into the national standards of all member countries, superseding the previous 1988 edition. The standard is maintained by committees like CEN/TC 459/SC 12 within the European Committee for Standardization (CEN).
The standard is the fundamental European regulation that establishes the definitions and classification of steel grades. If you are searching for an "EN 10020 PDF," you are likely looking for the framework that determines whether a steel is classified as non-alloy , stainless , or other alloy steel . What is EN 10020?
This European Standard defines the classification and designation of steels. It applies to all types of steels, including carbon, alloy, and stainless steels.
The standard is a fundamental European document that provides the definition and classification of steel grades based on their chemical composition and quality classes. It is essential for engineers and manufacturers to ensure they are using the correct type of steel for specific industrial applications. Core Classification Framework
The mechanical properties include:
: Often referred to as carbon steels. For a steel to be "non-alloy," the content of any single element must not reach a specific limit defined in the standard (e.g., Manganese < 1.65%, Silicon < 0.60%, Copper < 0.40%).
EN 10020 functions as a foundational vocabulary rulebook. It does not provide the technical delivery conditions for ordering specific steel plates or bars. Instead, other European standards rely on its definitions to assign designations:

EN 10020 divides steels into three major groups:
The standard serves a dual purpose. First, it acts as a dictionary, providing strict definitions for terms like "steel," "grade," and "chemical composition." Second, it acts as a map, categorizing steels into three main groups based on their chemical properties and intended application. For engineers, procurement officers, and metallurgists, accessing the EN 10020 PDF is often the first step in verifying material certifications or selecting the appropriate material for a specific application.
The standard is widely used in various industries, including:
Beyond chemical composition, EN 10020 further categorizes steel based on its intended properties, quality, and areas of application. This "quality class" system is crucial for ensuring the right material is used for the right purpose. Given the immense variety of steel, with properties

standard is a critical European regulation that provides the official definition and classification of steel grades
Instead of dealing with specific mechanical properties (which are covered by specific product standards like EN 10025 or EN 10088), EN 10020 establishes the and quality traits that define all European steels. 1. Definition of Steel According to EN 10020
