EN 10020 is a critical European Standard with the full title "Definition and classification of grades of steel." It serves as the foundational document that defines, once and for all, what the term "steel" actually means and provides a systematic way to classify the thousands of different steel grades available on the European market.
: Simple non-alloy steels with no specific heat treatment requirements. en 10020 pdf
These grades require higher purity (lower levels of sulfur and phosphorus) and precise control over mechanical properties. They are often intended for specific heat treatments like quenching and tempering or case hardening. Alloy Steel Quality Classes EN 10020 is a critical European Standard with
Steels where the content of any individual element does not reach a specific threshold limit (e.g., Manganese < 1.65%, Silicon < 0.60%, or Chromium < 0.30%). They are often intended for specific heat treatments
The designation system consists of:
