Manufacturing plants must reference EN 10020 during quality audits to prove that their material sorting and documentation practices align with European regulatory frameworks.
If you need to find an for a European grade?
The core of the EN 10020 standard is its classification system, which organizes steels into three principal categories. This hierarchy allows for a logical grouping of materials based on their primary characteristics.
(the exact mass percentage of alloying elements).

You can also purchase from CEN’s national members in your country (e.g., ANSI in the US, SNZ in New Zealand, SABS in South Africa). They all sell the exact same content, just with a national wrapper.
, is the foundational European document that establishes how all steels are categorized based on their chemical composition and quality characteristics.
This is the most referenced part of the standard. EN 10020 classifies steel into three main groups:
: Separating steels into distinct compositional groups and assigning quality classes tied directly to their intended application capabilities. Understanding the Three Main Steel Classes
