standard, titled "Definition and classification of grades of steel"

The designation system consists of:

Design: Helping engineers align material expectations (like weldability or heat treatment response) with the standardized quality-class approach.

Non-alloy special steels: Feature higher purity (lower sulfur and phosphorus) and consistent response to heat treatment.

The EN 10020:2000 standard is a critical European document that defines and classifies grades of steel. It establishes a uniform framework for identifying steel based on its chemical composition and quality characteristics. Key Classifications under EN 10020

2. Classification by Chemical Composition (Clause 4)

This is the most referenced part of the standard. EN 10020 classifies steel into three main groups:

Furthermore, the standard is essential for regulatory compliance. In pressure equipment (PED), construction products (CPR), and automotive standards, materials must meet specific "grade" requirements as defined by EN 10020 to be legally sold within the European Economic Area.
