Non-alloy steels are often called carbon steels. They contain very small amounts of other elements. EN 10020 lists strict limit values for these steels. For example, a steel is non-alloy if it has less than: 1.65% Manganese 0.40% Silicon 0.30% Chromium 0.30% Nickel 2. Alloy Steels

The standard serves two primary functions: defining what qualifies as "steel" (Clause 2) and providing a hierarchical classification for different steel grades (Clauses 3-4). en 10020 pdf

These are defined as steels containing at least and a maximum of 1.2% Carbon. They are specifically valued for their corrosion and heat resistance. 3. Other Alloy Steels Non-alloy steels are often called carbon steels
