Material Number Standard Range of Application Standard Status Country Predecessor Application temperature [°C]
A4L-70 (DIN EN ISO 3506-1 : 2020-08) DIN EN ISO 3506-1 : 2020-08 Supersedes DIN EN ISO 3506-1 : 2010-04 Valid Germany Property Class A4L-70 -60 - 150 1)
1) Remark: Non-stabilized austenitic steels of grade A4 are "acid proof steels", which are Mo alloyed and give a considerably better resistance to corrosion (boiling sulfuric acid, to a certain extent to chloride containing environment). Lower limit of operational temperature for headless screws: -200 °C Application: cellulose industry, food industry, shipbuilding, bolts and nuts acc. to DIN 267-13
