: Steels where at least one element exceeds the specific threshold limits set for non-alloy steels, used for specialized properties like high-temperature strength or wear resistance. Chemical Thresholds for Alloying Elements Classification is determined by the minimum value
To define what constitutes "steel" based on carbon and alloy content.
The core functionality of EN 10020 is classifying steel by its chemical composition based on the ladle analysis. A. Non-alloy Steel en 10020 pdf
By establishing uniform definitions, the standard eliminates confusion across international supply chains, ensuring that a specific grade ordered in one European country meets the exact chemical and structural criteria when manufactured in another. Core Definitions: What is Steel According to EN 10020?
Alloy steels intended for applications where the requirements are higher than standard non-alloy but lower than special steels. : Steels where at least one element exceeds
Search for localized versions (such as DIN EN 10020 for Germany, BS EN 10020 for the UK, or SIST EN 10020 for Slovenia) through your national standards organization.
These typically have no special requirements for response to heat treatment or microstructural cleanliness. BS EN 10020 for the UK
Steels featuring higher purity than quality steels, often with precise control over non-metallic inclusions. They are typically intended for quenching and tempering or surface hardening. Stainless Steel Quality Classes:
Under EN 10020, steel is categorized into three main groups based on the mass percentages of alloying elements. The standard defines specific boundary limits for elements like manganese, silicon, chromium, nickel, and molybdenum.
