StahlWissen Database

More than 425,000 records. Over 2000 licenses. In 25 countries worldwide: Our database StahlWissen® was created a good quarter of a century ago - thanks to constant further development, it is now state-of-the-art when it comes to steel and its heat treatment. StahlWissen® gives you access to the most up-to-date material data with references and offers simulation technology at the highest level!


The ability to set very different properties by specific heat treatments, is one of the outstanding characteristics of steel. The variety of steel grades and the different process possibilities in heat treatment were the reason for developing a material database more than 30 years ago, which meets the special requirements of an operational heat treatment. The database StahlWissen® offers comprehensive information for heat treaters, materials engineers, designers and Interested parties from the fields of quality assurance, standardization and materials purchasing and sales in industry, science, education and business.


Search and find the right material for your application in over 400,000 data sets.


Compare the properties of the materials in a simple way.

Data as a Service
