Enables accurate mapping between European steel numbers (per EN 10027) and international equivalents like ASTM, AISI, or JIS standards. To help find the right documentation, please let me know:
The European standard EN 10020 is the foundational document that defines and classifies steel grades across Europe. This standard provides a consistent, objective framework for manufacturers, engineers, and purchasers to categorize steel based on chemical composition and quality main stages. 1. What is EN 10020?
The most fundamental way to categorize steel is by analyzing the chemical elements that make it up. According to EN 10020, steel is a material where the weight percentage of iron is higher than that of any other element, and its carbon content (C) is less than 2%, which is the usual boundary between steel and cast iron. From there, the standard divides steel into three principal classes:

Before classifying different types of steel, EN 10020 outlines the boundary between steel and other iron-based materials. According to the standard, steel is a material in which the mass percentage of iron is greater than that of any other single element, and the carbon content is generally less than 2%.
Engineers and professionals often look for the document to:
These are defined as steels containing at least and a maximum of 1.2% Carbon. They are specifically valued for their corrosion and heat resistance. 3. Other Alloy Steels Enables accurate mapping between European steel numbers (per

The standard also defines a coding system for steel grades, which consists of a combination of letters and numbers that provide information about the steel's composition and properties.
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. According to EN 10020, steel is a material
