According to EN 10020, non-alloy steel is defined by having a low content of alloying elements, below specified limits. For instance, the content of elements such as manganese, silicon, or nickel must be below specific percentage thresholds. 2. Stainless Steels
However, the standard provides crucial nuances to this definition. It distinguishes between:

To distinguish between non-alloy and alloy steels, EN 10020 sets specific weight percentage thresholds for various elements: Limit Value (% by mass) Aluminium (Al) Chromium (Cr) Copper (Cu) Manganese (Mn) Nickel (Ni) Silicon (Si) 2. Main Quality Classes
The standard is generally available through official standards providers like the British Standards Institution (BSI). Core Classifications in EN 10020:2000 According to EN 10020, non-alloy steel is defined
Ensuring products meet the legal requirements for European structural and manufacturing standards.

The core functionality of EN 10020 is classifying steel by its chemical composition based on the ladle analysis. A. Non-alloy Steel
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 standard categorizes steel into three main groups based on chemical composition:
EN 10020 does not exist in isolation. It is part of a family of European steel standards:
