Alloy steels intended for applications where the requirements are higher than standard non-alloy but lower than special steels.
Classified by Nickel content (< 2.5% or ≥ 2.5%) and specific properties (corrosion, heat resistance). Quality Steels
This standard is essential for industries working with steel, as it provides a clear and concise way of designating and classifying steel grades, ensuring that materials meet specific requirements and are used appropriately.
Investing in an official copy ensures that your engineering team relies on accurate data, protecting your production line from costly compliance issues. Share public link en 10020 pdf
This class includes high-performance steels characterized by precise chemical control and exceptional cleanlines. It covers:
EN 10020:2000 is more than just a document—it is the foundational classification system upon which modern European steel specifications are built. Its definitions for non-alloy, stainless, and other alloy steels, as well as its distinction between quality and special materials, ensure clarity and consistency across the continent's manufacturing, construction, and engineering sectors.

EN 10020:2000 applies to non-alloy steel grades, which are defined as steels that do not contain any deliberate additions of alloying elements, such as chromium, nickel, or molybdenum. The standard covers steel grades used for general engineering purposes, including:
For engineers, metallurgists, and quality control professionals, precise classification of steel is essential. EN 10020:2000 is the definitive European standard that establishes a common language for defining and categorizing steel grades. This detailed article explains everything you need to know about EN 10020, its classifications, and how to obtain the official PDF document.
: Steels that do not meet the definition of stainless steel but have at least one alloying element exceeding the limit for non-alloy steel. Main Quality Classes Definition of "Steel"
The standard is indispensable for the correct identification and classification of steel. By separating steels into non-alloy, stainless, and other alloy categories, and by further breaking them down by quality class, it provides a crucial reference point for engineers worldwide. Ensuring you are using the correct version of the EN 10020 PDF ensures compliance and performance in any engineering application.
These include alloy engineering steels, tool steels, high-speed steels, and steels designed for high-pressure vessels or bearings.
