There are more than 2,500 standardized types of steel worldwide, which differ in their composition, manufacturing and post-treatment processes and therefore also in their intended use. Almost 400 of these materials are also produced in our rolling mills. Finding your way around often costs time and nerves.
Our material database should save you time and nerves and make the material search easier.
If you already know the required material, simply use our search function. For example, search for the short name, EN, AISI or UNS. Under Details you will also find the detailed data sheet, which is also available for download.
Further information on using the material database can be found here.
