Identify how stainless steel is classified based on Nickel content
Whether you are a seasoned metallurgist or a student taking your first materials science course, is the foundation of steel classification in Europe and beyond. It saves time, prevents costly errors, and ensures that everyone—from the steel mill to the construction site—speaks the same language.
EN 10020:2000 - Definition & Classification of Steel - iTeh Standards

Beyond chemical composition, the standard further categorizes steels into quality classes based on their intended application and properties:
(the exact mass percentage of alloying elements).
If you are reviewing a PDF copy of BS EN 10020 , pay close attention to these critical sections: Identify how stainless steel is classified based on
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%.
: High-purity steels often intended for quenching and tempering or specific surface treatments. Why the PDF is Essential for Engineers Accessing the full EN 10020 PDF is critical for:
Limited amounts of other elements are allowed, but the essential property is that iron is the dominant constituent. 2. Classification by Chemical Composition (Clause 3) If you are reviewing a PDF copy of
EN 10020 defines stainless steels as alloys containing a minimum of and a maximum of 1.2% carbon . They are classified further by their microstructure:
Ensuring that suppliers provide the correct grade of steel according to European standards.
: Steels that do not meet the definition of stainless steel but have at least one alloying element exceeding the limit for non-alloy steel. Main Quality Classes
