EN 10020:2000

The standard is a fundamental European document that provides the definition and classification of steel grades based on their chemical composition and quality classes. It is essential for engineers and manufacturers to ensure they are using the correct type of steel for specific industrial applications. Core Classification Framework

• Non-alloy steels: Where specific limits on certain elements (like chromium, nickel, or molybdenum) are not exceeded.
• Alloy steels: Where the content of one or more specific elements exceeds defined limits.

EN 10020 PDF

When a steel mill issues a certificate of compliance (e.g., EN 10204 3.1 or 3.2), it will reference the relevant product standard (e.g., EN 10025 for structural steels). Behind that product standard, the definition of "steel" and its classification rely on EN 10020. Thus, having the on hand ensures you can trace the definitions back to the source. en 10020 pdf

1. Procurement Accuracy: When writing a material specification sheet, referencing EN 10020 ensures that the supplier cannot substitute a lower-grade "non-alloy" steel for a "special" steel, as the chemical boundaries are strictly defined in the text.
2. Cross-Referencing: Older national standards (like DIN in Germany or BS in the UK) are often replaced by EN standards.

Beyond chemical makeup, EN 10020 classifies steels by their "quality class," which refers to their intended application and required properties: EN 10020:2000 The standard is a fundamental European
