: High-purity steels often intended for quenching and tempering or specific surface treatments. Why the PDF is Essential for Engineers Accessing the full EN 10020 PDF is critical for:
is the foundational European standard that establishes the official definition of steel and outlines how steel grades are systematically classified . Finding an official EN 10020 PDF is a critical first step for metallurgists, procurement specialists, and structural engineers who need a globally harmonized framework to identify, buy, or test steel materials across international supply chains. The standard categorizes all steels based on their exact chemical compositions and performance classes, eliminating confusion when interpreting technical datasheets.
The standard divides steel into three primary groups based on chemical composition:
: These are basic steels. They do not need special heat treatment. They are used for simple parts and structural builds.
is a European standard that provides a basic definition of steel and establishes a clear classification system for steel grades based primarily on their chemical composition . en 10020 pdf
For your professional, research, or certification needs, the official PDF of is an indispensable resource. While several online platforms offer the document for sale, obtaining it from an official national standards body is the best way to ensure you have the most up-to-date, accurate, and legally compliant version of this crucial standard.
Defines exactly what counts as "steel" based on its chemical mix.
A Comprehensive Guide to EN 10020: Definition and Classification of Grades of Steel
Whether you are an engineer trying to certify a material or a procurement manager sourcing alloy steel, understanding how to navigate an ensures that you can accurately interpret chemical compositions and quality classes. What is EN 10020? : High-purity steels often intended for quenching and
According to EN 10020, non-alloy steel is defined by having a low content of alloying elements, below specified limits. For instance, the content of elements such as manganese, silicon, or nickel must be below specific percentage thresholds. 2. Stainless Steels
Used in applications like structural components, rails, or electrical sheets. They are alloyed for specific physical performance but aren't intended for highly demanding core heat treatments.
By respecting and correctly applying EN 10020, you ensure that the steel you buy is the steel you intended to receive—no guesswork, no disputes, just engineering certainty.
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 categorizes all steels based on their
They are characterized by standard mechanical properties and a typical microstructure. Special Steels
Once the chemical category is determined, EN 10020 further refines the steel into quality classes based on its intended property profiles and manufacturing care. Non-Alloy Steel Quality Classes:
EN 10020 mandates that steel grades must be divided into three major categories based on their chemical composition: non-alloy steels, stainless steels, and other alloy steels. The distinction is made by evaluating the specified ladle analysis against precise boundary values. 1. Non-Alloy Steels
Steels with at least 10.5% chromium and a maximum of 1.2% carbon.
This standard does not specify individual steel properties for ordering. Instead, it acts as an umbrella framework. Other standards, such as EN 10025 (for structural steels) or EN 10088 (for stainless steels), rely directly on the classification principles defined in EN 10020. Core Classification Criteria
This "catch-all" category encompasses alloy steels that do not fall under the stainless classification. It includes:
