EN 10020, titled "Definition and classification of grades of steel," establishes the precise terminology used to distinguish steel from other ferrous materials. It replaces older national standards (such as the German DIN or British BS systems) with a unified European approach. The primary objective of the standard is twofold:
Beyond chemistry, the standard looks at how the steel is intended to be used: Non-alloy Quality Steels:
Steel is divided into three main groups based on the percentage of alloying elements: Non-alloy steels: en 10020 pdf
standard is the European regulation that defines and classifies grades of steel based on their chemical composition and quality categories. If you are looking for an "EN 10020 PDF," you are likely looking for the technical breakdown of how steel is officially categorised in the industry. What is EN 10020? The standard, titled "Definition and classification of grades of steel,"
This residual category encompasses all steel grades that contain specific alloying elements in amounts exceeding the limits for non-alloy steels but do not necessarily meet the chromium threshold for stainless steel. This includes high-strength low-alloy (HSLA) steels, tool steels, and other specialized materials. EN 10020, titled "Definition and classification of grades
Note: A few chromium-based tool steels may contain more than 2% carbon, but 2% remains the standard line of demarcation between steel and cast iron. 2. Classification by Chemical Composition
Prevents errors when ordering raw materials or specifying grade requirements in international contracts. If you are looking for an "EN 10020
EN 10020 is a European Standard (EN) titled “Classification and designation of steel grades.” Published by the European Committee for Standardization (CEN), it establishes the rules for how steels are defined, classified, and designated based on their chemical composition.
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
If the carbon content exceeds 2.06%, the material is classified as cast iron (not covered by this standard).
