Alloy steels are formulated with intentional additions of elements like chromium, nickel, or molybdenum to enhance specific mechanical or physical properties (such as tensile strength, hardness, or corrosion resistance). 4. Classification by Quality Class

The European standard EN 10020 is the foundational document that defines and classifies steel grades across Europe. This standard provides a consistent, objective framework for manufacturers, engineers, and purchasers to categorize steel based on chemical composition and quality main stages. 1. What is EN 10020?

, is the foundational European document that establishes how all steels are categorized based on their chemical composition and quality characteristics. en 10020 pdf

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

Steels containing at least 10.5% Chromium and a maximum of 1.2% Carbon. Other Alloy Steels: Alloy steels are formulated with intentional additions of

: Segregating steels based on precise alloy mass thresholds.

The standard primarily divides steels based on their chemical composition and quality characteristics: EN 10020:2000 - Definition & Classification of Steel This standard provides a consistent, objective framework for

Steels where the concentration of alloying elements does not exceed specific limits defined by the standard.

Used in applications like structural components, rails, or electrical sheets. They are alloyed for specific physical performance but aren't intended for highly demanding core heat treatments.

EN 10020 further divides steels based on intended use and quality characteristics:

Clear classification prevents disputes regarding whether a material should be tariffed or tested as a "carbon" or "alloy" steel.
