"Steel classification according to EN 10020:2000 (E) – Definition and classification of grades of steel."
By primary property (e.g., corrosion-resisting, heat-resisting, or creep-resisting). Other Alloy Steel Quality Classes:
: Sets the exact "Table 1" values that determine if a material is officially considered "alloyed" or "non-alloyed". Normative Reference : Often used alongside
Beyond composition, EN 10020 further categorizes steels based on their intended use or quality requirements, which often determines the steel's processing route (e.g., cleanliness, grain size control).
This residual category encompasses all steel grades that contain specific alloying elements in amounts exceeding the limits for non-alloy steels but do not necessarily meet the chromium threshold for stainless steel. This includes high-strength low-alloy (HSLA) steels, tool steels, and other specialized materials. en 10020 pdf
Understanding and applying EN 10020 is not merely an academic exercise; it has significant practical consequences across multiple industries.
Helping engineers align material expectations (like weldability or heat treatment response) with the standardized quality-class approach.
The designation of steels consists of:
This "catch-all" category encompasses alloy steels that do not fall under the stainless classification. It includes: "Steel classification according to EN 10020:2000 (E) –
EN 10020 is the bedrock of European metallurgy. While it may appear to be a dry technical document, its influence extends across the entire manufacturing supply chain. By providing a rigorous definition of steel and a logical classification system, it eliminates ambiguity, facilitates international trade, and ensures safety in engineering. Whether accessed as a physical handbook or a digital "EN 10020 PDF," the standard remains an essential resource for anyone involved in the specification, processing, or application of steel. It transforms a chaotic array of metallic alloys into a structured, understandable, and manageable material science.
The core of the EN 10020 standard is its classification system, which organizes steels into three principal categories. This hierarchy allows for a logical grouping of materials based on their primary characteristics.
EN 10020 is not a material specification (it does not give mechanical properties). Instead, it:
According to EN 10020, steel is defined as a material in which iron is the predominant element, and where the carbon content is generally less than 2% by weight. It may contain other elements, but the carbon threshold is a primary differentiator from cast iron (which typically contains more than 2% carbon). This residual category encompasses all steel grades that
To obtain a legitimate, current version of the EN 10020 PDF, you should purchase it through authorized national standardization bodies or reputable distributors, such as: (British Standards Institution) DIN (German Institute for Standardization) AFNOR (French National Organization for Standardization) ISO Store or regional European standard platforms
Standardization bodies do not typically provide these documents for free. To obtain a legitimate EN 10020 PDF, you should visit official portals such as: DIN (German Institute for Standardization) CEN (European Committee for Standardization)
In the complex world of metallurgy and engineering, communication is just as critical as composition. If a structural engineer in France orders steel from a manufacturer in Germany, both parties must agree precisely on what constitutes "non-alloy steel" versus "alloy steel." This is where comes into play.
