Steels featuring higher purity than quality steels, often with precise control over non-metallic inclusions. They are typically intended for quenching and tempering or surface hardening. Stainless Steel Quality Classes:
Possessing the official document is vital for several reasons:
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. en 10020 pdf
These are alloy structural steels used in applications like automotive components or pressure vessels where specific mechanical properties are required, but processing demands are standard. Examples include weldable fine-grained structural steels.
For any professional dealing with steel—whether you are negotiating a contract, preparing a welding procedure specification (WPS), or simply trying to understand a material certificate—EN 10020 is the Rosetta Stone of steel grades. Steels featuring higher purity than quality steels, often
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).
The standard uses a specific limit for each element to separate them. If a steel has more than the limit of a certain metal, it becomes an alloy steel. 1. Non-Alloy Steels If a structural engineer in France orders steel
The intended application and performance characteristics. 1. Classification by Chemical Composition
