standard (specifically EN 10020:2000 ) provides the definitive definition and classification of grades of steel
within the European framework. It is the foundational document used to categorize steel based on chemical composition and quality levels. Key Features and Classifications
The standard divides all steels into two primary categories based on their chemical makeup: Non-Alloy Steels
: Steels where the percentage of alloying elements does not exceed specific limits defined in the standard's reference tables. Base Steels
: General purpose steels with no special quality requirements. Quality Steels
: Steels requiring closer control of properties like grain size or formability. Special Steels
: High-purity steels with precise control over composition and inclusion content. Alloy Steels
: Steels that contain at least one element at or above the specified threshold. Stainless Steels : Defined as having at least 10.5% Chromium and a maximum of 1.2% Carbon Other Alloy Steels
: Further sub-classified into quality or special steels based on their intended use and properties. www.ranger.com.hk Technical Utility Interoperability

The EN 10020 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?
EN 10020, titled "Definition and classification of grades of steel," serves as the dictionary for the European steel industry. It ensures that manufacturers, engineers, and buyers across the EU use a unified language when categorizing steel products based on their chemical composition. Core Classification Criteria
The standard classifies steel into three main categories based on the mass percentage of alloying elements:
Non-alloy Steels: 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%).
Stainless Steels: Defined as steels containing at least 10.5% Chromium and a maximum of 1.2% Carbon. These are further sub-divided based on their properties (corrosion resistance, heat resistance, etc.).
Other Alloy Steels: 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
Beyond chemical composition, EN 10020 categorizes steel by its intended use and quality:
Base Steels (Non-alloy): General-purpose steels without specific heat treatment requirements. Base Steels: Steels that are generally not intended
Quality Steels: Steels requiring closer control of properties like grain size or formability.
Special Steels: 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:
Material Selection: Ensuring a chosen grade meets regulatory definitions for a project.
Compliance: Verifying that a supplier’s "non-alloy" steel actually fits the technical definition.
Tendering: Accurately describing materials in technical specifications to avoid procurement errors. How to Access the Standard
Standardization bodies do not typically provide these documents for free. To obtain a legitimate EN 10020 PDF, you should visit official portals such as: BSI (British Standards Institution) DIN (German Institute for Standardization) CEN (European Committee for Standardization)
You can use this for documentation, a website, or a technical reference sheet.
1. Non-Alloy Steels
Often referred to as carbon steels, this category covers the vast majority of steels produced globally. Under EN 10020, a steel is considered "non-alloy" if the content of specific elements (like chromium, nickel, manganese, etc.) does not exceed a specific threshold (e.g., Manganese < 1.65%, Silicon < 0.60%).
Within this category, EN 10020 further distinguishes between:
- Base Steels: Steels that are generally not intended for heat treatment and have limited properties.
- Quality Steels: Steels where specific requirements (like toughness, grain size, or formability) are necessary.
- Special Steels: High-grade steels designated for specific applications, often with higher purity or tighter controls on properties.
3. Main Classification Categories
EN 10020 divides steels into three major groups:
