Mechanical properties of stainless steel for metric DIN 933 Hexagon Head Cap Screws / Bolts Full Thread

Stainless steels can be divided into three groups of steel – austenitic, ferritic and martensitic. Austenitic steel is by far the most common type (>90% of commercial fasteners). The steel groups and strength classes are designated by a four-digit sequence of letters and numbers (eg A2-70) as shown in the following table. DIN EN ISO 3506 governs screws and Bolts made from stainless steel.jjj
