BS en 10020 Definition and Classification of Grades of Steel
That is why the European Committee for Standardization made the standard. This document defines what steel is. It also groups steel into clear categories based on what the steel is made of and how it will be used. en 10020 pdf
They are born for extreme conditions—fighting off rust, surviving brutal heat, and holding up under massive pressure. 📍 Chapter 2: The Quest for Stainless Purity As the liquid
The weight percentage of alloying elements. : Details the exact chemical limits for classification
How this standard interacts with (the naming system for steels)? Information on a specific steel grade (like S235 or S355)? EN 10020:2000 - Definition & Classification of Steel
: High-purity steels with precise control over chemical composition and non-metallic inclusions, often intended for quenching and tempering. EN 10020:2000 - Definition & Classification of Steel This document defines what steel is
: Steels where the percentage of alloying elements does not exceed specific limits defined in the standard's reference tables. Base Steels
If you download a legitimate , you will find three major sections. Let’s break them down.
: These are the cleanest non-alloy steels. They have very low amounts of phosphorus and sulfur. They react very well to heat treatments. Quality Classes for Alloy Steels
: Grades where at least one element exceeds the limit specified for unalloyed steel, but which do not meet the definition of stainless steel. Main Quality Classes
