| « Material standards | The SS material standards (e.g. SS 14 23 53) each comprise one steel grade only, and this grade has the same designation as the standard. The first two digits indicate that the standard concerns a steel and they can mostly be left out.
The standards specify forms of supply, chemical composition, mechanical properties, heat treatment (however the temperature is not stated) and types of certificate for the documentation of the testing results. Furthermore, corrosion testing is specified with the requirements to be met.
After the steel designation, there is a condition number, e.g. SS 2353-22. This number indicates the form of supply, the finish and, where applicable, the technical terms of delivery.
Examples of condition numbers:
