Information On British Standard Steels BS EN 10025

Important Notes:
All information on this page has been interpreted from the relevent standards, books, other web sites, andl leaflets.     This information is of a general nature for initial guidance.    Selection of materials for design use must be by communication with the suppliers and by reference to the relevant standards.
The tables below include for composition , proof strength , tensile strength and elongation.    The mechanical properties are generally related to room temperature     The information is not comprehensive and must be used with extreme care.    The relevant standards include detailed notes on the conditions relevant to the properties and also a large quantity of detail information on other properties including hardness values impact values and properties at higher and lower temperatures
