The standard divides all steels into two primary categories based on their chemical makeup: Non-Alloy Steels
Once the chemical group is determined, EN 10020 further categorizes steels by their quality and performance characteristics. Non-Alloy Steel Quality Classes en 10020 pdf
: Feature higher purity (lower sulfur and phosphorus) and consistent response to heat treatment. The standard divides all steels into two primary
When searching for the , always ensure you are getting the 2020 edition . Using an outdated version could lead to misclassification and non-conformance. Using an outdated version could lead to misclassification
The standard is also instrumental in international trade, environmental reporting, and quality assurance systems. For instance, the European Commission's Joint Research Centre (JRC) and the EU Emissions Trading System (EU ETS) reference the chemical composition limits established by EN 10020 to define materials like "EAF carbon steel" and "EAF high alloy steel." This consistency is vital for accurate data collection and fair market practices.
