You can also purchase from CEN’s national members in your country (e.g., ANSI in the US, SNZ in New Zealand, SABS in South Africa). They all sell the exact same content, just with a national wrapper. , which covers the actual naming (designation) system
standard (specifically EN 10020:2000 ) provides the definitive definition and classification of grades of steel
Here are some of the key EN 10020 steels:
The standard divides steel into three primary categories based on its chemical makeup and the concentration of specific alloying elements. How to Access the Standard must be measured
| Steel Grade | Steel Number | | --- | --- | | S235 | 1.0037 | | S355 | 1.0045 | | C45 | 1.0503 |
Steels containing a minimum of 10.5% Chromium and a maximum of 1.2% Carbon by weight. They are characterized by their corrosion resistance.
Without a standard like EN 10020, a steel grade labeled "C45" in Germany might be interpreted as "1045" in the USA or "080M46" in the UK. EN 10020 provides the framework to map these designations to a consistent definition.
Also referred to as , these contain mostly iron and carbon. For a steel to be classified as non-alloy, the content of alloying elements must remain below specific limit values defined in the standard. Manganese (Mn): Typically limited to 1.65%. Silicon (Si): Limited to 0.50%.
