BS EN 10020 2000 — DEFINITION AND CLASSIFICATION OF GRADES OF STEEL
|D O W N L O A D|
Quite clear, this British Standard deals with the classification and definition of steel grades. It was prepared by Technical Committee ECISS/TC6 and replaces the standard EN 10020:1988 which is now considered obsolete. The document consists of the four chapters - scope - term and definition - classification by chemical composition - classification of main quality classes.
The first two parts provide some standard definitions that are in use by BS EN. The part dealing with the chemical composition tells readers about the alloy contents, definition of alloy classes, stainless and non-alloy steels, as well as of the other alloy steels. The last part describes the non-alloy quality and special steels, stainless steels, other alloy steels and allow quality and special steels from the classification viewpoint. The table in the booklet describes boundary between alloy and non-alloy steels (specified elements vs limit values).
Another table is dedicated to the weldable fine grained alloy steels. The standard takes into account all latest developments in the iron and steel industry as well as recent progress in EU standardization so will definitely be useful and practical.
