The EN 10020 standard is the primary European reference for the definition and classification of steel grades. It provides the fundamental framework used across the industry to categorize steel based on its chemical composition and quality characteristics. Core Purpose and Scope

Common Mistakes When Using EN 10020

After helping hundreds of buyers and engineers, these are the top three errors: en 10020 pdf

| Element | Non-Alloy Steel (max %) | Alloy Steel (min %) | |---------|------------------------|---------------------| | Cr | < 0.30 | ≥ 0.30 | | Ni | < 0.30 | ≥ 0.30 | | Mo | < 0.05 | ≥ 0.05 | | V | < 0.05 | ≥ 0.05 | | Cu | < 0.40 | ≥ 0.40 | | W | < 0.10 | ≥ 0.10 | The EN 10020 standard is the primary European

Non-alloy steels: Steels where the percentage of each element is below a specific limit defined in the standard. Non-alloy steels: Where specific limits on certain elements

• 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.

Alloy Quality Steels: Used for general structural or pressure purposes where specific mechanical properties are required but without the extreme purity of special steels.

8. Revision Status

• Current version: EN 10020:2000 (confirmed in 2015, 2020)
• No new revision as of 2025; remains valid.
• Supersedes earlier: EN 10020:1991

While the initial cost of the PDF may seem high, the cost of misclassifying a steel batch (e.g., using non-alloy steel in an alloy-special application) can lead to catastrophic failure, product recall, or legal action.
