Table according to DIN 933, ISO 4017
DIN (Deutsches Institut für Normung – German Institute for Standardization) standards are issued for a variety of components including industrial fasteners as Metric DIN 933 Hexagon Head Cap Screws / Bolts. The DIN standards remain common in Germany, Europe and globally even though the transition to ISO standards is taking place. DIN standards continue to be used for parts which do not have ISO equivalents or for which there is no need for standardization. IN this case the ISO equivalent for DIN 933 is ISO 4017.
1) 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 nuts made from stainless steel.
