       Stainless steels can be divided into three groups of steel - austenitic. ferritic and martensitic. Austenitic steel is by far the 

 

mostcommon type (>90% of commercial fasteners). The steel groups and strength classes are designated by a four-digit

 

sequenceof letters and numbers (eg A2-70) as shown in the following table. DIN EN ISO 3506 governs screws and nuts made

 

fromstainless steel.
