Steels are classified based on their chemical composition and/or mechanical properties.

These include alloy engineering steels, tool steels, high-speed steels, and steels designed for high-pressure vessels or bearings.

Non-alloy steels are often called carbon steels. They contain very small amounts of other elements. EN 10020 lists strict limit values for these steels. For example, a steel is non-alloy if it has less than: 1.65% Manganese 0.40% Silicon 0.30% Chromium 0.30% Nickel 2. Alloy Steels

Understanding EN 10020 is essential for anyone involved in the steel supply chain. Here is why:

Higher purity (lower P and S limits); precise response to heat treatment. By Composition en 10020 pdf

Steels that do not meet the definition of stainless steel but have at least one element exceeding the non-alloy limits. 4. Classification by Main Quality Classes

Defines exactly what counts as "steel" based on its chemical mix.

EN 10020 is widely used in the European steel industry as a reference for specifying and ordering steel products. Steels are classified based on their chemical composition

: Available through the BSI Shop (British Standards Institution) or iTeh Standards .

Generally intended for standard structural applications, general engineering, and components where extreme or highly specialized properties are not the primary focus.

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

If you want to find out more about how this standard affects your specific project, I can help. Tell me: What are you building? They contain very small amounts of other elements

These are steels where at least one of the elements exceeds the limit value, but which do not meet the chromium and carbon criteria to be classified as stainless steel. This category includes a vast range of engineering steels, tool steels, and high-strength low-alloy (HSLA) steels.

EN 10020 is a standard published by the European Committee for Standardization (CEN) that provides a classification system for steel grades. The standard is titled "Steel - Classification" and it was last updated in 2000.
