Rely on the right type of
stainless steel
Metal structure

Hello ,

With more than 100 different types of stainless steel, it is not always easy to keep the overview and select the right material. First of all, stainless steels are divided into three groups with different advantages and disadvantages: austenitic, ferritic and martensitic. 

Ferritic stainless steels have only moderate corrosion resistance and cannot be hardened by heat treatment, but they are cold formable. They are also highly magnetic.

Martensitic stainless steels are particularly strong because they can be hardened by heat treatment. However, most martensitic steel grades cannot be welded and are only suitable for mild corrosion conditions.

Austenitic stainless steels are the most common and have the widest range of applications. They are characterized by their comparatively high corrosion resistance. The austenitic stainless steel group also has various classifications. Our example illustrates how you can identify the steel groups and the strength classes using the four-digit sequence of letters and numbers.
