This catch-all category includes all steels that do not fall into non-alloy or stainless categories. Typically, this means steels where:
Divided into stainless steels with nickel less than 2.5% and 2.5% or more.
Once the chemical class (non-alloy or alloy) is determined, EN 10020 further divides the material into main quality classes based on its intended use, manufacturing care, and property reliability. Quality Classes for Non-Alloy Steels en 10020 pdf

Beyond chemical composition, EN 10020 introduces a sub-classification based on the quality and intended application of the steel. Main Quality Classes for Non-Alloy Steels
Used in applications like structural plates, rails, and tubing where specific mechanical properties are required, but processing demands are moderate.
: Explicitly defines the term "steel" as a material containing more iron than any other single element.
